[FR] A binding that prompts user to select from multiple options

[carbon-steel]

I think it'd be very handy to have a binding that prompts the user to select an option for example, something like:

bind status R !git rebase %(select: --continue|--abort|--edit-todo)

When you use this binding, tig would prompt the user (in some form) to select one of the three options before running the command. Perhaps each option could be selectable by a key ('c' for --continue, 'a' for --abort, etc).

Another option would be to allow multi-key bindings like:

bind status Rc !?git rebase --continue
bind status Re !?git rebase --edit-todo
bind status Ra !?git rebase --abort

But I prefer the first approach since it requires less memorization on the user's part.
