Nice.

For what it is worth, your SCCS supports merging just fine.  We used
SCCS to do merges without copying by using your includes.  If SCCS had
had a -m for merge, it would have included the branch but then all the
other deltas going up to the GCA.  Much like the tip means the tip
but all the other deltas going back to 1.1.

SCCS was a big contribution to the state of the art, I am forever
grateful that you did it.  To this day I don't think people know
what you did.  When we were a business, every time some SCM came out,
Rick or I would ask "is there a weave" like you had done, if not,
we didn't care.  That weave format that you did 50 years ago is
awesome.
