patch 9.1.0047: issues with temp curwin/buf while cmdwin is open
Problem: Things that temporarily change/restore curwin/buf (e.g:
win_execute, some autocmds) may break assumptions that
curwin/buf is the cmdwin when "cmdwin_type != 0", causing
issues.
Solution: Expose the cmdwin's real win/buf and check that instead. Also
try to ensure these variables are NULL if "cmdwin_type == 0",
allowing them to be used directly in most cases without
checking cmdwin_type. (Sean Dewar)
Alternatively, we could ban win_execute in the cmdwin and audit all places that
temporarily change/restore curwin/buf, but I didn't notice any problems arising
from allowing this (standard cmdwin restrictions still apply, so things that may
actually break the cmdwin are still forbidden).
