D3084: heads: add support for specying branches by revset

REVISION SUMMARY
  Before this commit, e.g. "hg heads .^" would fail with:
  
    abort: unknown revision '.^'!
  
  Like the previous patch, I don't care about the command itself (I
  don't think I had ever used it before), I'm just cleaning up uses of
  repo[<string>].
