[PATCH 00 of 12] RFC: Overlay repositories

Here's an RFC implementation of overlay repositories. These are
repositories that refer to a parent repository for revisions that
aren't available locally. There's a page on the idea at


At the moment the overlay repository instantiates the parent when it
is instantiated. I'd like to defer this until the time that older
revisions are actually used, but I haven't gotten to that yet.

There's also no attempt here to handle missing revisions. That'd be
nice at some point.
