* testing/lisp/test-org-agenda.el (test-org-agenda/tags-sorting): New
test.
---

Hello!

I just recently sent in a patch to add a new possible value for
`org-tags-sort-function'.  To ease discussion there, I thought I'd add a nice
little test here so I can later show off the feature I'm trying to add.

Do notice that TODO I put in the comment though.  Not sure what the solution to
that should be.

It would be nice to accept this patch even with the TODO so I can make patches
in the other discussion that extend this test.  Or I suppose I could try being
patient.  That doesn't sound as fun though.

Thanks,

Morgan
