Yikes.  If _that_ is the case, then fine.  Make them treated the same way.

Basically, I think they should (1) both be special and treated the same, 
or (2) only treat uppercase as special.

In an ideal world, I choose #2. In reality, I choose #1, because I don't 
want to break more dialplans that we have to.
