Do we want to do anything with the other dependency hole I found here:

  http://article.gmane.org/gmane.comp.version-control.git/215211

It's definitely a potential problem, but I don't think we have any
reports of it happening in practice, so it might not be worth worrying
about. Doing a clean version of the fix here:

  http://article.gmane.org/gmane.comp.version-control.git/215212

would probably involve reorganizing our .depend directory structure,
unless somebody can cook up some clever use of make's patsubst.
