Ctrl+Enter can try to accept empty git commit

Hello, friends!
There is a little problem, that annoying me. I used to accept commits with ctrl+enter hotkey. When I try to accept empty commit (no message or no files were staged) the button "Commit x/y File(s)" is disabled, but ctrl+enter still works. After pressing ctrl+enter on empty commit there appears message box about closing git editor. If I press esc (I would like to close message and continue editing) the editor closes.

IMHO it would be nice to inform me, that I'm trying to accept empty commit, but not ask to close the editor.
