Scan of broken conditional forms

[Mattias Engdegård]

Out of curiosity, I scanned the Emacs sources for useless conditional forms, 
like (if C X X) where both branches are the same, and found a few. Some look 
like unfinished code, but a several appear to be clear bugs. (I'm guilty of the 
one in autorevert.el, now fixed.)

In particular, the code in mml-smime.el looks like it fails to return failure 
from an unsuccessful encryption attempt. That can't be good.
