tui: Do not optimize left motion at the right margin.
From observation, there are several different possible behaviours:
1. Deferred wrap like a real DEC VT. The cursor stays visible in the last
column, and CUB is calculated relative to that column.
Examples: xterm, Unicode rxvt, PuTTY, nosh console-terminal-emulator,
FreeBSD kernel's built-in emulator, Linux's built-in emulator
2. Deferred wrap like a real DEC VT. CUB is calculated relative to the last
column. But the cursor is invisible.
Examples: emulators using newer libvte
3. Non-deferred wrap. The cursor has already wrapped to the next line and CUB
does not wrap back.
Examples: cygwin, Interix
4. Non-deferred wrap that acts like deferred wrap. The cursor has already
visibly wrapped to the next line, but CUB can wrap back around the left
margin.
Examples: Konsole
5. Deferred wrap with visibly out of bounds cursor. The cursor visibly moves
outwith the screen boundaries. CUB is calculated relative to a cursor
column that has overflowed the end of the screen grid array.
Examples: iTerm2
6. Deferred wrap with invisibly out of bounds cursor. CUB is calculated
relative to a cursor column that has overflowed the end of the screen grid
array. And the cursor is invisible.
Examples: emulators using older libvte
In many cases, nvim does not have enough information to know which behaviour
the terminal will exhibit, and thus the correct amount of CUB to issue.
