[FEATURE REQUEST] - extend git request-pull to send email

Hi,

The command "git request-pull" doesn't actually request anything but
just outputs a nice report about pending changes.
I would suggest to extend "git request-pull" to be able to send email
with the information generated by the command using "git send-mail"
functionality. By default it could take some values from the
environment, like the sender information, the subject and of course
the body of the message.

Specifying the "--to user@server.com" could be a trigger for this functionality.
All additional parameters from git send-mail should be available.

What do you think?


Thanks,
Eugene
