[darcs-devel] darcs patch: add an unused RepoFormat module.

Why not something like ``baseline'' ?

Yes, it's the natural place to put it.

No.  The reason why the repository abstraction makes integrating the
RepoFormat a triviality is that I've changed all the commands to only
manipulate repositories through the abstraction.  So in darcs-git, you
only need to modify identifyRepository to get all the commands to
check the repo format; in plain Darcs, you'll need to modify all the
commands.

The other side of the coin is that you cannot get the benefits of the
restructuring without pulling the changes to all the commands.

I'm not sure what should be done...  If you do a manual integration of
RepoFormat into every Darcs command, you'll be duplicating my work,
and I'll get massive merge conflicts when I merge with you.

That's okay.  I'll write a human-readable tutorial next week.
