doc: mouse: cleanup, fixup

- Much of the mouse chatter in gui.txt and term.txt is redundant; other
  parts are outdated or irreleveant to Nvim.
- Fix default value of 'mousemodel' for Windows

-3. Mouse Control					*gui-mouse*
-
-The mouse only works if the appropriate flag in the 'mouse' option is set.
-When the GUI is switched on, and 'mouse' wasn't set yet, the 'mouse' option is
-automatically set to "a", enabling it for all modes except for the
-|hit-enter| prompt.  If you don't want this, a good place to change the
-'mouse' option is the "gvimrc" file.
-
-Other options that are relevant:
-'mousefocus'	window focus follows mouse pointer |gui-mouse-focus|
-'mousemodel'	what mouse button does which action
-'mousehide'	hide mouse pointer while typing text
-'selectmode'	whether to start Select mode or Visual mode
-
-A quick way to set these is with the ":behave" command.
-							*:behave* *:be*
-:be[have] {model}	Set behavior for mouse and selection.  Valid
-			arguments are:
-			   mswin	MS-Windows behavior
-			   xterm	Xterm behavior
-
-			Using ":behave" changes these options:
-			option		mswin			xterm	~
-			'selectmode'	"mouse,key"		""
-			'mousemodel'	"popup"			"extend"
-			'keymodel'	"startsel,stopsel"	""
-			'selection'	"exclusive"		"inclusive"
-
-In the $VIMRUNTIME directory, there is a script called |mswin.vim|, which will
-also map a few keys to the MS-Windows cut/copy/paste commands.  This is NOT
-compatible, since it uses the CTRL-V, CTRL-X and CTRL-C keys.  If you don't
-mind, use this command: >
-	:so $VIMRUNTIME/mswin.vim
-
-For scrolling with a wheel on a mouse, see |scroll-mouse-wheel|.

-3.1 Moving Cursor with Mouse				*gui-mouse-move*
-
-Click the left mouse button somewhere in a text buffer where you want the
-cursor to go, and it does!
-This works in	    when 'mouse' contains ~
-Normal mode	    'n' or 'a'
-Visual mode	    'v' or 'a'
-Insert mode	    'i' or 'a'
-
-Select mode is handled like Visual mode.
-
-You may use this with an operator such as 'd' to delete text from the current
-cursor position to the position you point to with the mouse.  That is, you hit
-'d' and then click the mouse somewhere.
-
-							*gui-mouse-focus*
-The 'mousefocus' option can be set to make the keyboard focus follow the
-mouse pointer.  This means that the window where the mouse pointer is, is the
-active window.  Warning: this doesn't work very well when using a menu,
-because the menu command will always be applied to the top window.
-
-If you are on the ':' line (or '/' or '?'), then clicking the left or right
-mouse button will position the cursor on the ':' line (if 'mouse' contains
-'c', 'a' or 'A').
-
-In any situation the middle mouse button may be clicked to paste the current
-selection.
-
-
-3.2 Selection with Mouse				*gui-mouse-select*
-
-The mouse can be used to start a selection.  How depends on the 'mousemodel'
-option:
-'mousemodel' is "extend": use the right mouse button
-'mousemodel' is "popup":  use the left mouse button, while keeping the Shift
-key pressed.
-
-If there was no selection yet, this starts a selection from the old cursor
-position to the position pointed to with the mouse.  If there already is a
-selection then the closest end will be extended.
-
-If 'selectmode' contains "mouse", then the selection will be in Select mode.
-This means that typing normal text will replace the selection.  See
-|Select-mode|.  Otherwise, the selection will be in Visual mode.
-
-Double clicking may be done to make the selection word-wise, triple clicking
-makes it line-wise, and quadruple clicking makes it rectangular block-wise.
-
-See |gui-selections| on how the selection is used.
-
-
-3.3 Other Text Selection with Mouse		*gui-mouse-modeless*
-						*modeless-selection*
-A different kind of selection is used when:
-- in Command-line mode
-- in the Command-line window and pointing in another window
-- at the |hit-enter| prompt
-- whenever the current mode is not in the 'mouse' option
-- when holding the CTRL and SHIFT keys in the GUI
-
-Since Vim continues like the selection isn't there, and there is no mode
-associated with the selection, this is called modeless selection.  Any text in
-the Vim window can be selected.  Select the text by pressing the left mouse
-button at the start, drag to the end and release.  To extend the selection,
-use the right mouse button when 'mousemodel' is "extend", or the left mouse
-button with the shift key pressed when 'mousemodel' is "popup".
-The selection is removed when the selected text is scrolled or changed.
-
-On the command line CTRL-Y can be used to copy the selection into the
-clipboard.  To do this from Insert mode, use CTRL-O : CTRL-Y <CR>.  When
-'guioptions' contains a or A (default on X11), the selection is automatically
-copied to the "* register.
-
-The middle mouse button can then paste the text.  On non-X11 systems, you can
-use CTRL-R +.
-
-
-3.4 Using Mouse on Status Lines				*gui-mouse-status*
-
-Clicking the left or right mouse button on the status line below a Vim
-window makes that window the current window.  This actually happens on button
-release (to be able to distinguish a click from a drag action).
-
-With the left mouse button a status line can be dragged up and down, thus
-resizing the windows above and below it.  This does not change window focus.
-
-The same can be used on the vertical separator: click to give the window left
-of it focus, drag left and right to make windows wider and narrower.
-
-
-3.5 Various Mouse Clicks				*gui-mouse-various*
-
-    <S-LeftMouse>	Search forward for the word under the mouse click.
-			When 'mousemodel' is "popup" this starts or extends a
-			selection.
-    <S-RightMouse>	Search backward for the word under the mouse click.
-    <C-LeftMouse>	Jump to the tag name under the mouse click.
-    <C-RightMouse>	Jump back to position before the previous tag jump
-			(same as "CTRL-T")
-
-
-3.6 Mouse Mappings					*gui-mouse-mapping*
-
-The mouse events, complete with modifiers, may be mapped.  Eg: >
-   :map <S-LeftMouse>     <RightMouse>
-   :map <S-LeftDrag>      <RightDrag>
-   :map <S-LeftRelease>   <RightRelease>
-   :map <2-S-LeftMouse>   <2-RightMouse>
-   :map <2-S-LeftDrag>    <2-RightDrag>
-   :map <2-S-LeftRelease> <2-RightRelease>
-   :map <3-S-LeftMouse>   <3-RightMouse>
-   :map <3-S-LeftDrag>    <3-RightDrag>
-   :map <3-S-LeftRelease> <3-RightRelease>
-   :map <4-S-LeftMouse>   <4-RightMouse>
-   :map <4-S-LeftDrag>    <4-RightDrag>
-   :map <4-S-LeftRelease> <4-RightRelease>
-These mappings make selection work the way it probably should in a Motif
-application, with shift-left mouse allowing for extending the visual area
-rather than the right mouse button.
-
-Mouse mapping with modifiers does not work for modeless selection.

-4. Making GUI Selections				*gui-selections*

-							*quotestar*
-You may make selections with the mouse (see |gui-mouse-select|), or by using
-Vim's Visual mode (see |v|).  If 'a' is present in 'guioptions', then
-whenever a selection is started (Visual or Select mode), or when the selection
-is changed, Vim becomes the owner of the windowing system's primary selection
-(on MS-Windows the |clipboard| is used).
-
-							*primary-selection*
-There is a special register for storing this selection, it is the "*
-register.  Nothing is put in here unless the information about what text is
-selected is about to change (e.g. with a left mouse click somewhere), or when
-another application wants to paste the selected text.  Then the text is put
-in the "* register.  For example, to cut a line and make it the current
-selection/put it on the clipboard: >
-
-	"*dd
-
-Similarly, when you want to paste a selection from another application, e.g.,
-by clicking the middle mouse button, the selection is put in the "* register
-first, and then 'put' like any other register.  For example, to put the
-selection (contents of the clipboard): >
-
-	"*p
-
-Note that when pasting text from one Vim into another separate Vim, the type
-of selection (character, line, or block) will also be copied.  For other
-applications the type is always character.
-
-When the "unnamed" string is included in the 'clipboard' option, the unnamed
-register is the same as the "* register.  Thus you can yank to and paste the
-selection without prepending "* to commands.

 Using the mouse						*mouse-using*
 
-This section is about using the mouse on a terminal or a terminal window.  How
-to use the mouse in a GUI window is explained in |gui-mouse|.  For scrolling
-with a mouse wheel see |scroll-mouse-wheel|.
-
-These characters in the 'mouse' option tell in which situations the mouse will
-be used by Vim:
-		n	Normal mode
-		v	Visual mode
-		i	Insert mode
-		c	Command-line mode
-		h	all previous modes when in a help file
-		a	all previous modes
-		r	for |hit-enter| prompt
-
-If you only want to use the mouse in a few modes or also want to use it for
-the two questions you will have to concatenate the letters for those modes.
-For example: >
-	:set mouse=nv
-Will make the mouse work in Normal mode and Visual mode. >
-	:set mouse=h
-Will make the mouse work in help files only (so you can use "g<LeftMouse>" to
-jump to tags).
-
-Whether the selection that is started with the mouse is in Visual mode or
-Select mode depends on whether "mouse" is included in the 'selectmode'
-option.
-
-In an xterm, with the currently active mode included in the 'mouse' option,
-normal mouse clicks are used by Vim, mouse clicks with the shift or ctrl key
-pressed go to the xterm.  With the currently active mode not included in
-'mouse' all mouse clicks go to the xterm.
-
-							*xterm-clipboard*
-The middle mouse button will insert the unnamed register.  In that case, here
-is how you copy and paste a piece of text:
-
-Copy/paste with the mouse and Visual mode ('mouse' option must be set, see
-above):
-1. Press left mouse button on first letter of text, move mouse pointer to last
-   letter of the text and release the button.  This will start Visual mode and
-   highlight the selected area.
-2. Press "y" to yank the Visual text in the unnamed register.
-3. Click the left mouse button at the insert position.
-4. Click the middle mouse button.
-
-Shortcut: If the insert position is on the screen at the same time as the
-Visual text, you can do 2, 3 and 4 all in one: Click the middle mouse button
-at the insert position.
-
-							*xterm-copy-paste*
-NOTE: In some (older) xterms, it's not possible to move the cursor past column
-95 or 223.  This is an xterm problem, not Vim's.  Get a newer xterm
-|color-xterm|.
-
-Copy/paste in xterm with (current mode NOT included in 'mouse'):
-1. Press left mouse button on first letter of text, move mouse pointer to last
-   letter of the text and release the button.
-2. Use normal Vim commands to put the cursor at the insert position.
-3. Press "a" to start Insert mode.
-4. Click the middle mouse button.
-5. Press ESC to end Insert mode.
-(The same can be done with anything in 'mouse' if you keep the shift key
-pressed while using the mouse.)
-
-Note: if you lose the 8th bit when pasting (special characters are translated
-into other characters), you may have to do "stty cs8 -istrip -parenb" in your
-shell before starting Vim.
-
-Thus in an xterm the shift and ctrl keys cannot be used with the mouse.  Mouse
-commands requiring the CTRL modifier can be simulated by typing the "g" key
-before using the mouse:
-	"g<LeftMouse>"	is "<C-LeftMouse>	(jump to tag under mouse click)
-	"g<RightMouse>" is "<C-RightMouse>	("CTRL-T")

 							*bracketed-paste-mode*
-Bracketed paste mode allows terminal applications to distinguish between typed
-text and pasted text. Thus you can paste text without Nvim trying to format or
