'inccommand' preview callback.
Solution: Don't set an invalid 'undolevels' value.

Problem: 'inccommand' doesn't restore 'undolevels' properly for a
buffer shown in multiple windows.
Solution: Don't save information of a buffer twice.
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.

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'.

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.

Problem: Multibyte characters may be wrapped at the end of a line
when 'statuscolumn' and 'spell' are set.
Solution: Update line pointerdiff "v" before fetching the line pointer
after evaluating 'statuscolumn'.
