Martin's response assumes that you have Foo, AlbertFoo, BethFoo and
CarolFoo in separate repositories.  So you push changes from repo
containing Foo to some common locations for AFoo, BFoo and CFoo to
pull or let them pull from the repo containing Foo.  But I think you
mean to have all of them in the /same/ repo and still be able to
update ?Foo with changes from file Foo.  I do not think this is
supported by any in-built mechanism, though It may not be impossible
to hack together some custom solution tying together diff, patch
etc. called by post-commit hook.  Ugh.

What is the use case?
