I've added a help topic called config and referenced it using the error
message suggested by Greg above:

  http://hg.intevation.org/mercurial/crew/rev/b52f0f221325
  http://hg.intevation.org/mercurial/crew/rev/951730b2b8ba

As mentioned in the commit message, I plan to move more/all of hgrc.5
into the help system -- I already have the code for parsing line blocks
so I think we're almost there.
