- Reverse the meaning of the *-prefix in the :module and :browse
  commands: '*Foo' now means the full contents of Foo, whereas just
  'Foo' means Foo's exports only.  This seems more intuitive to me,
  but the downside is that ':m Foo' doesn't do the same thing in
  GHC as Hugs (you have to say ':m *Foo' to get Hugs's behaviour).
