Windows has "Read and execute" permission via ACL
but nvim and libuv do not support ACL.
Windows does not support the executable bit in chmod-style permissions
but it is safe to assume that if the file exists and is readable,
then it is most likely executable.
This means that win.ini and shell32.dll are "executable"
because they exist, are readable, and are in PATH.
PATHEXT does not affect the executable permission of a file;
it exists to run files on the shell while omitting the file extension.
Assume that PATHEXT is intended for cmd.exe only
because powershell can execute powershell files (ie. *.ps1)
without changing PATHEXT or related cmd.exe environment variable.
In the future, nvim should check the outputs of 'assoc' and 'ftype',
cmd.exe internal commands, or check the registry.
Powershell can be used for ACL if C++/C# API is too difficult to use.
The old code could lead to a memory error in the following situation:
0. The previous cursor position was row 50 since before, on a grid
larger than 50 rows.
1. grid_resize changes the grid height to 40, and invalidly assumes the
resize moved the physical cursor to row 0
2. Some event used a operation that could move the cursor (such as clear), and
then reset the cursor to the "true" position row 50 (pointless after #8221, but
I forgot to remove it)
3. raw_line/cheap_to_print is invoked, and tries to inspect the grid at
row 50 (memory error)
4. grid_cursor_goto would have been called at this point, and set a
valid cursor position 0-39.

Problem: Cannot use :unlet for an environment variable.
Solution: Make it work. Use unsetenv() if available.

It fails with `nvim -u NONE -c 'set modified' -c 'confirm q'`.
Introduced in 3dffc842f (vim-patch:8.0.0983), but the Vim patch [1] does not
have this assertion.
NULL gets handled in `dialog_msg` [2].

Problem: Nasty autocommand causes using freed memory. (Dominique Pelle)
Solution: Do not force executing autocommands if the value of 'syntax' or
'filetype' did not change.

Problem: Weird autocmd may cause arglist to be changed recursively.
Solution: Prevent recursively changing the argument list. (Christian

The scrolling region is always local to a single grid_scroll event, use
local variables and parameters instead.
The invocation of reset_scroll_region in grid_resize is cargo-culted to use
margin reset under exactly the same circumstances, not sure if it is necessary
though.
The statusline may incorporate b:term_title, so redraw it when that
title changes.
Introduce a new function status_redraw_buf to redraw windows associated
with the current buffer.
When building with -DEXITFREE, the ILOG call would result in a crash
trying to access VV_PROGPATH, which had already been released:
