nnn exit codes (filepicker)

[vlappa]

Another idea from fzf. It has several exit codes which could be useful for nnn when in filepicker mode, useful for scripting.

From fzf:

       0      Normal exit
       1      No match
       2      Error
       130    Interrupted with CTRL-C or ESC

Don't think there's any plans for it. Keep in mind that nnn is a file-manager first and foremost. The picker mode was an afterthought. Whereas fzf was designed ground up as a picker.
