I'd tried this earlier and it was returning no results... but it turns
out I hadn't made the TreeWalker recursive.  Setting it as recursive
fixes that problem... but I'd prefer to not get results from the
subdirs of my subdir.  I think the only option is to give the
TreeWalker trees with the root set to my subdir, and not use
recursion.  Any other options?  Can I get a subdir tree from the
repository?
