Actually, I think that assertion has an off-by-one error, it should be

  eassert (tlen >= file_name_as_directory_slop + 1);

If I change it this way, the recipe finishes and returns an empty
string.  Does anyone see a problem with making such a change on
master?  (I still think that we don't need to make any changes on the
release branch.)

Thanks.
