I wish someone would tell me I'm wrong but imenu doesn't support any
kind of heirarchy.  You're getting a "Section" menu that contains a
bunch of "setup" entries without any indication of which subtest it
belongs to right?

AFAIK, the best you can do is to specify () or nil for the menu names
and include the testcase/subtest/section keyword in your match group.
Obviously, then, you can't use any sorting on the imenu index because
it's only the position in the list that gives you an idea of what
groups your entities belong to.

I've been trying to find time to enhance imenu myself because I have
several modes that need hierarchy support but it's just not happening.
If someone else has done something I'll be downloading it right away
but I've not seen anything.
