Subject: git-send-email: SIG{TERM,INT} handlers
X-Git-Tag: v1.5.5-rc0~229^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=874299760708e3bd4d63e9afa8da3fe8a7ddc006;p=git.git

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

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.
