Command-line CTRL-U, CTRL-Y

[justinmk]

ref #1

• CTRL-U in cmdline-mode stores in the @- register
• CTRL-Y in cmdline-mode yanks from the @- register

@tpope Fully implemented ctrl-w and ctrl-u. General idea is to compare getcmdline() before & after using Vim's built-in ctrl-u/ctrl-w. Also verified that this works with multibyte characters in various combinations.

[justinmk]

Used this approach similar to <C-T> below, because <c-\>e was causing unpleasant flicker.

@tpope I've been using this for a couple weeks without issue. What are your thoughts? I can add <M-BS> too if appropriate.

What are the chances of this ever getting merged in? It would be really nice to use C-u

[justinmk]

I can send an updated PR without the CTRL-W stuff. After using it for a long time I think CTRL-W is more trouble than it is worth. For it to be useful it needs to "append" as readline does, and that would be a lot of fiddly code. However CTRL-U is definitely useful and works without issue.

Also there's a question of what CTRL-U should do in insert-mode: should it also store in @- register?

[justinmk]

Updated. Now only maps CTRL-U and CTRL-Y.

I worry a bit about re-purposing @-, but I guess I'll give it a try.
