This is a sort of simplified version of git-review[1] for users like
myself who don't mind most git command line tools, and therefore don't
feel the need to switch to a full git-review workflow, but still don't
like the HEAD:refs/for/master%r=user@domain.com syntax for specifying
reviewers during a push.
Reviewer aliases can be specified in a git config file:
[reviewer]
sop = sop@google.com
$ git push-reviewer --dry-run sop
git push origin HEAD:refs/for/master%r=sop@google.com
