From: Paul Fox <pgf@xxxxxxxxxxxxxxxxxxxx>
The user's editor likely catches SIGINT (ctrl-C). but if
the user spawns a command from the editor and uses ctrl-C to
kill that command, the SIGINT will likely also kill git
itself (depending on the editor, this can leave the terminal
in an unusable state).
