Then I must have misunderstood your request.

What should be the semantics, then?  Let me have a stab.

      * If there's no directory passed, use "." as the destination.
      * If there's a directory passed, use it as the destination.
      * If the destination doesn't exist, create it.
      * If the destination already contains a .hg directory, error out.

What if we run "hg init" inside an existing repository?  This case
should probably be skipped, as it would make it impossible to revision-
control $HOME and have repositories in there.
