REVISION SUMMARY
  Many places were doing repo[mark], which usually works, but it's
  slightly incorrect: if the bookmark has a name that matches a full hex
  nodeid of another node, then the context for the other node will be
  returned instead. Also, I'm about to remove support for
  repo[<namespace thing>] :)
