Ok, I just pushed out a fix which should get this right (it introduces a new "base_name_compare()" function that knows about these subtleties).

I guess we should add a proper ordering test for all these cases. There's:
 - exact same name, directory vs file
 - different length names, but same in the first characters
	- this one has the subcases of the next character sorting with '/' 
	  or '\0' depending on the type of the shorter filename.

Your previous test handled only the simple "exact same name" case.
