Problem:  matchparen keeps cursor on case label in sh filetype
          (@categorical, after 9.1.1187).
Solution: Use :defer so that cursor is always restored, remove checks
          for older Vims, finish early if Vim does not support :defer

Most callers of feed() do not expect feed() to dedent.
Now use a literal space in tests where it looks better.

Problem:  Cmdline pum not cleared for input() completion.
Solution: Temporary reset RedrawingDisabled in cmdline_pum_cleanup(),
          like what is done in wildmenu_cleanup() (zeertzjq).

No code change is needed in Nvim, as RedrawingDisabled does not prevent
the compositor from removing a grid.

Problem:  matchparen plugin wrong highlights shell case statement
          (Swudu Susuwu)
Solution: return early, if we are in a shSnglCase syntax element

The shell syntax element "case $var in foobar)" uses closing parenthesis
but there is no corresponding opening parenthesis for that syntax
element. However matchparen is not aware of such things and will happily
try to match just the next opening parenthesis.

So let's just add a way to opt out for such cases. In this case, use the
syntax state to check if the closing parenthesis belongs to the syntax
item "shSnglCase" and if it is, do not try to find a corresponding
opening parenthesis.

Since inspecting the syntax state might be expensive, put the whole
check behind a filetype test, so that matchparen will only perform this
particular check, when it knows the current buffer is a "sh" filetype.

Problem:    Sourcing buffer lines is too complicated.
Solution:   Simplify the code. Make it possible to source Vim9 script lines.
            (Yegappan Lakshmanan, closes vim/vim#9974)

https://github.com/vim/vim/commit/85b43c6cb7d56919e245622f4e42db6d8bee4194

This commit changes the behavior of sourcing buffer lines to always have
a script ID, although sourcing the same buffer always produces the same
script ID.

vim-patch:9.1.0372: Calling CLEAR_FIELD() on the same struct twice

Problem:  Calling CLEAR_FIELD() on the same struct twice.
Solution: Remove the second CLEAR_FIELD().  Move the assignment of
          cookie.sourceing_lnum (zeertzjq).

Problem:
Indenting text is a common task in plugins/scripts for
presentation/formatting, yet vim has no way of doing it (especially
"dedent", and especially non-buffer text).

Solution:
Introduce `vim.text.indent()`. It sets the *exact* indentation because
that's a more difficult (and thus more useful) task than merely
"increasing the current indent" (which is somewhat easy with a `gsub()`
one-liner).
