Why separate that stuff? Why not just store the URL? The repository_URL
passed to RA->open is simply the URL associated with the topmost, common
directory.

The separate "repository" and "path" is following CVS's pattern for no good
reason... it is an artificial separation.

"http://www.lyra.org/products/glorb/foo.c" is the path. I'd say that we
simply store it that way.

This will be especially important if we end up with a file that comes from a
different repository. I'm not sure whether you store the URL for a subdir
in "./SVN/entries" or in "subdir/SVN/entries", but we definitely mix
repositories on a per-directory basis. If the URL is stored in ".", then
they definitely have to be mixable.

[ hmm. it appears that you store ancestry for a subdir in "." ]
