Oh, that's actually not necessary. I put it in so I could re-run the 
test without restarting emacs or manually resetting the advice, and I 
forgot to remove it.

Probably true. I wasn't sure how much I would end up using it, and it 
seemed like a potentially useful macro to have lying around when testing 
advice that might break core functions of emacs.

Anyway, I wasn't very creative with my test names or function names, and 
I'd be happy to submit a new patch with more informative names (as well 
as the above changes). Is there a naming convention for tests/functions 
that I should adhere to?
