[Feature Request] Vim mode in debugger interface

[erikw]

It would be great if fingers used to Vim-like navigation could command the delve debugger TUI e.g. like <esc>kki which would go up to lines in the history and enter insert mode again.

I'm used to this with other repl/debuggers like iPython, IRB, ghci etc.

Is delve using readline for the debugger TUI input? Then this would come for free when having set editing-mode vi in ~/.inputrc (did not work though so I assume not).
