It might make sense, if you wanted to refer to remote repositories. But
granted, I don't see an easy way to implement cat() on files in remote
repositories for the Mercurial-plugin.

I will provide a patch for review, which willl move merge() and the
complex diff() to centralvcs and reduce the diff() in basicvcs to work
only on local-files and revisions.
