The symbolize-directory test right next to it would be perfect (and, in fact, this code derives from that).

Except it deals with the directory entry zero, which is unallowed in dwarf4 and required in dwarf5, which makes sharing the source file between the two a bit of a pain. It's also testing something important, so needs to stay.
