> I've been investigating this on the emacs side as well. At the moment, my suspicion is that ^G causes emacs to trigger (keyboard-quit), but at the same time the surrounding environment (e.g. git) is sending a SIGINT to emacs, which normally acts like ^G but in this case may be triggering the emergency exit mode of emacs. Is there some reason that the interactive add would be sending SIGINT to emacs when I type ^G?

If you are using text mode (-nw) then Emacs redefines the INTR character
of the terminal to ^G.  On the other hand it should also put itself into
its own process group, so the parent should not receive the terminal
signals.  And this is what happens here when I try it.

Andreas.
