In the past, this has always gotten bogged down in the realization
that we need to consult with a zillion other version control projects
and come up with a common patch format that supports tree- and
metadata-changes as well as straight diff data. In other words, a
patch format that supports the union of all the operations all these
version control systems support.

This is perfectly possible, of course, just hard.

Do we want to give up on that goal? Do we want to come up with our
own parseable format that we know will work for Subversion, and then
later if a common patch format develops (with or without our
involvement), we can add an option to produce it?
