[Feature Request] Undo in Command-line mode

You can undo from Insert mode with <C-o>u. So, does this solve your problem?

:imap <C-_> <C-o>u

Want to use in cmdline mode, this seems did not work.

I have no plans to implement this personally, but if someone PRs it I would be glad to merge.

FWIW, I think the simplest way to implement this would be to keep an undo stack with snapshots of the command line, updated every time we make an edit and perhaps occasionally in response to normal user edits. AFAIK Neovim does not support undo in the command line.
