Whoops, nothing was broken.  I started thinking about how to handle this if the
base names use git hashes instead of svn revisions, but I didn't finish it.  I'm
going to revert this snippet, we can address the sorting issue separately.

Ah. fwiw the bootstrap zip file uses the git number, not the svn revision
number.  So by design this relies on the filename not being a git hash.
