+------------------
+XXX: there is a bug in interactive selection as it is not letting to examine the
+file. Tried with curses too. In the curses UI, if you just unselect the hunks
+and the not file mod thing at the top, it will show the same "nothing unselected
+to uncommit" message which is a bug in interactive selection.
