This means a different binding for "C-x C-c" depending on situation,
and the binding to save-buffers-kill-terminal depending on a minor
mode.  Previously, "C-x C-c" would do its job regardless of the mode.
I'm not sure this is for the best.  I'd be interested to hear from
others, if anyone has an opinion.
