git-send-email: SIG{TERM,INT} handlers

Browse Source 
A single signal handler is used for both SIGTERM and
SIGINT in order to clean up after an uncouth termination
of git-send-email.

In particular, the handler resets the text color (this cleanup
was already present), turns on tty echoing (in case termination
occurrs during a masked Password prompt), and informs the user
of of any temporary files created by --compose.
