I think after a couple of releases you'd be shipping something like

	foo--1.0.sql
	foo--1.1.sql
	foo--1.0--1.1.sql
	foo--2.0.sql
	foo--1.1--2.0.sql

and it'll soon get to be a mess if your SCM doesn't clearly distinguish
which is which.

Also, as I mentioned before, once you've branched off foo--1.1.sql
it's probably a mistake to be changing foo--1.0.sql anymore anyway.

I suppose if you really wanted foo.sql to always be the head version,
you could do something like "cp foo.sql foo--$VERSION.sql" as part of
the build process in the Makefile.
