The old behaviour (e.g. via `set display-=msgsep`) will not be available.
Assuming that messages always are being drawn on msg_grid
(or not drawn at all, and forwarded to `ext_messages` enabled UI)
will allows some simplifcations and enhancements moving forward.
This was used in the past with assumption that curwin/curbuf
is "special" but this has not been true since basically forever
at this point.
Reduce NOT_VALID/CLEAR panic in options.lua . These should not
be set if an effect of the option is causing something
which by itself invokes redraw_later().
When :undo! was introduced to Nvim the implementation of 'inccommand'
preview callback hasn't been fully decided yet, so not notifying buffer
update callbacks made sense for 'inccommand' preview callback in case it
needs to undo the changes itself.
Now it turns out that the undo-and-forget is done automatically for
'inccommand', so it doesn't make sense for :undo! to avoid notifying
buffer update callbacks anymore.
Problem: Crash when closing a tabpage and buffer is NULL.
Solution: Adjust how autocommands are triggered when closing a window.

Problem: When at the command line :redrawstatus does not work well.
Solution: Only update the statuslines instead of the screen. (closesvim/vim#11180)

Problem: Cannot redraw the status lines when editing a command.
Solution: Only postpone the redraw when messages have scrolled.

Cherry-pick Test_redraw_in_autocmd() from Vim patch 8.2.4789.
Problem: Crash when invalid line number on :for is ignored.
Solution: Do not check breakpoint for non-existing line.

Test does not fail without the fix in Nvim as Nvim uses 0 when line
number overflows. If it is changed to MAXLNUM then the test does fail
without the fix, but using 0 seems better as E481 is still given.
Problem: ":wincmd =" equalizes in two directions.
Solution: Make ":vertical wincmd =" equalize vertically only and
":horizontal wincmd =" equalize horizontally only.

`!did_throw` doesn't exactly imply `!current_exception`, as `did_throw = false`
is sometimes used to defer exception handling for later (without forgetting the
exception). E.g: uncaught exception handling in `do_cmdline()` may be deferred
to a different call (e.g: when `try_level > 0`).
In #7881, `current_exception = NULL` in `do_cmdline()` is used as an analogue of
`did_throw = false`, but also causes the pending exception to be lost, which
also leaks as `discard_exception()` wasn't used.
It may be possible to fix this by saving/restoring `current_exception`, but
handling all of `did_throw`'s edge cases seems messier. Maybe not worth
diverging over.
This fix also uncovers a `man_spec.lua` bug on Windows: exceptions are thrown
due to Windows missing `man`, but they're lost; skip these tests if `man` isn't
executable.
Problem: Clearing screen causes flicker.
Solution: Do not clear but redraw in more cases. Add () to "wait_return".

set. (Christian Brabandt)
Solution: Do not give an error for an empty result. (closesvim/vim#10307)

Solution: Avoid an error for verbose expansion. Fix that the "0verbose"
command modifier doesn't work.

Use `.sn_name` instead of `->sn_name` as v8.2.0154 hasn't been ported.
Cherry-pick builtin.txt expand() doc from latest Vim.
Problem: The option.c file is too big.
