Problem:
The cmdpreview saved undo nodes on cmdpreview_prepare() from ex_getln.c may
become invalid (free) if the preview function makes undo operations, causing
heap-use-after-free errors.
Solution:
Save the buffer undo list on cmdpreview_prepare)_ and start a new empty one. On
cmdpreview_restore_state(), undo all the entries in the new undo list and
restore the original one. With this approach, the preview function will be
allowed to undo only its own changes.

Previously, when using foldmethod=indent, inserting an unindented line
would inadvertently open closed folds below it.
As a performance improvement, folds were only updated once, across all
lines, after Insert mode was exited.
Now, the performance improvement is no longer being used when
foldmethod=indent, so folds are updated multiple times during Insert
mode, but only across the lines that are changing, which preserves the
folds (and their open/close states) instead of recreating them.
Problem: screenpos() returns wrong row with diff filler lines.
Solution: Only add filler lines when appropriate. Also don't add the
'smoothscroll' marker when w_skipcol is zero. (closesvim/vim#12485,
closesvim/vim#12484)

Problem: screenpos() does not take w_skipcol into account.
Solution: Subtract w_skipcol from column. (closesvim/vim#12486, closesvim/vim#12476)

fix(ui): delay win_viewport until screen update #24182
Problem:
Sometimes, when nvim sends the `win_viewport` event, for example when scrolling
with visible folds on the screen, it reports the `scroll_delta` value one batch
into "future". So when the client application is trying to show the new viewport
it's not yet updated, resulting in temporary corruption / screen flickering.
For more details see #23609, and starting from [this comment](
https://github.com/neovide/neovide/pull/1790#issuecomment-1518697747) in
https://github.com/neovide/neovide/pull/1790,, where the issue was first
detected. Note that some of the conclusions in those are not fully accurate, but
the general observations are.
Solution:
When there are pending updates to a Window, delay the `win_viewport` UI event
until the updates are sent. This ensures that there's no flush between sending
the viewport and updating of the lines corresponding to the new viewport.
Document the existing viewport behaviour (for cases where there are no
extra flushes), give a hint about how applications can deal with the slightly
surprising behaviour of the viewport event being sent after the updates.

Problem: Cannot drag a vertical separator to the right of a window
whose 'statuscolumn' is wider than itself.
Solution: Never treat a click on a vertical separator as a click on
'statuscolumn'.
(cherry picked from commit c0007e6300)
Problem: Bashslashes added as regexp in runtime completion may be
treated as path separator with some 'isfname' value.
Solution: Make curly braces work for runtime completion and use it.

fix(api): nvim_cmd{cmd="win_getid"} parsed as :winsize
Problem:
`:lua vim.cmd.win_getid(30,10)` is interpreted as `:win[size] 30 10`.
User intention was to call `vim.fn.win_getid(30,10)`.
Solution:
Check that the `cmd` actually matches the resolved command.

Redrawing of 'statusline' and 'winbar' are actually already inhibited by
RedawingDisabled in Ex mode.
In Vim there is a check for `msg_scrolled == 0` (which is false in Ex
mode) since Vim doesn't have msgsep. Add a `!exmode_active` check here
in Nvim instead.

`nvim_cmd` shows multiple errors when attempting to edit another buffer
through a command when `curbuf->b_ro_locked` is set. This PR fixes that
by removing a redundant error in `execute_cmd`.

Problem: Quickfix text field is truncated.
