Settings > Version Control > Git > "Show branch and incoming/outgoing commits
in the Project view" (off by default) shows each repository root's branch and
its outgoing/incoming commit counts beside the root in the Project view. Git is
queried only after a change inside .git or when the set of roots changes, one
round at a time.
