[RFC] Script for isolating maintainer email.

[Alexandru Juncu]

Hello!

I found the need for a script that doesn't require me to copy part of the
output from get_maintainer.pl into git send-email and could do both with
one command.

I don't know if there is something similar already implemented. If there is,
please point me to it. If not, maybe somebody finds it useful.

Used on top of get_maintainer.pl, it generates the list of
emails required for git send-email.

The output can be used as a process expansion into the arguments of
git send-email. Example:

git send-email $(scripts/get_email.sh my.patch) my.patch
