Git tags are associated with the commit object, which in turn points a
the tree. So the development tree would consist of the whole of
coda/lwp/rpc2/rvm at the point in time that the tag is created.

Well, except that I'm trying to get away from using submodules. But it
may be moot because I just seem to hit problems in reposurgeon and the
git filter branch history rewriting afaik doesn't do what I would like.

Yes, I've mostly given up on trying to fix that except for the low
hanging fruit cases. At least operations like git blame can give some
idea of approximately when/why particular changes were made, it is
unlikely that a checkout of early versions will actually return a
tree that can be compiled without changes.

I have done that before with grafts and filter-branch, I do not remember
it as being too terribly hard.
