I guess I should take take back the following statement from my
previous thread,

The ambiguity persists. It seems that 'Add untracked' is not
differentiating between 'absence of untracked files' and 'not selecting
any untracked files' currently. It seems to be the root cause of the
ambiguity.

As a result the new message "No untracked file chosen." seems absurd
when user tries to choose the '4: add untracked' option in 'git add -i'
and there are no untracked files in his repository.

    $ git add -i

    *** Commands ***
      1: status    	      2: update    	      3: revert    	      4: add untracked
      5: patch    	      6: diff    	      7: quit    	      8: help
    What now> 4
    No untracked file chosen.
