Would be even better if the bannermsg told me what identifiers are
available.  E.g.

  loaded repo: <repo.root>
  using source: <mercurial.__path__>
  available identifiers: mercurial, repo, cl, mf

Also, you could add mercurial.__version__.version to the "using source" line.

Hmmm: is there really any value in making the 'mercurial' package
available?  Won't I still have to explicitly import other mercurial.*
modules that I'm interested in?
