EditMode Support?

[jeremyjh]

Hi, it doesn't look like this yet support's changing rustyline's EditMode. I really like vi bindings in my shell and would love to see that in crush. I'm willing to take a crack at implementing if I can get some guidance on how such options should be specified by the user, e.g. what should be the equivalent command to bindkey -v from ZSH?

Excellent question. Of the top of my head, it feels like configuring the editor should be it's own namespace, e.g editor, so re-doing a key binding could be something like editor:bind key=XX action=YY. Switching between emacs-mode and vi-mode would then be something like editor:mode "vi".

Added a very short and WIP-y intro to hacking Crush.

Please add to it. Or, when you're not sure what to add, let me know and I'll do my best, but I've found that documentation is often better when written by someone who is on the journey of finding information - they know better what the actually hard parts are. :-)
