Misc tools for working with git and Gerrit.

For now only git-cleanup.

Install with:

  $ go get github.com/bradfitz/gitutil/git-cleanup

Use like:

  $ git checkout master
  $ git sync                # aka git codereview sync
  $ git cleanup

(Assuming you're contributing to Go with git-codereview and Gerrit; see https://golang.org/doc/contribute.html)
