This is not quite doable by os.path.walk, since filename might be a single file.
Note that os.path.islink doesn't work right (i.e. detect aliases) on a Mac,
so this won't work if Mac aliases are present.
Error if filename is not an existing file or directory, but existence of non-directories is not checked.
If the second argument is given, it should be a list object of already-collected results,
