[PATCH] git-add--interactive: print message if there are no untracked files

[Alexander Kuleshov <kuleshovmail@gmail.com>]

If user selects 'add untracked' and there are no untracked files,
"Add untracked>>" opens. But it does not make sense in this case, because there
are no untracked files. So let's print message and exit from "add untracked" mode.
