An alternative route is to change Git (or subclass it, or whatever) and
set a source property when it's called and nothing has changed.

In fact I wanted to make further changes (to use a script we use instead
of using git clone), and (less trivially) to ignore local uncommitted
changes (some of our codebases change committed files during the build,
and I wanted to skip those).
