Does having a directory in sources work? I'd expect that this makes something
depend on the directory's timestamp, and if files in subdirectories of that
directory change, the top-level timestamp won't be updated and incremental
builds won't work correctly. Is there any way to list all the input files here?

Yes, this works because of the deps as well. See lines 638 above.
