Formats the last commit and sends emails to all members in the pull request group using standard sendmail. I wrote this because the builtin 'git send-email' does only allow to send a patch file which I think is killer in a small team development.

git pull-request

[pull-request]
  group = firstname@lastname.com firstname2@lastname2.com
[alias]
  pull-request = "!branch=$(git name-rev --name-only HEAD) ; echo \"git pull $(git remote) $branch\n\n $(git log -1 HEAD --stat)\" | mail -s \"Pull request: $branch\" $(git config pull-request.group)"
