Before I upload the new build, I want to make sure the problem really is 
fixed.  M-x help works fine, but then I tried some of the other things 
that the OP mentioned, and I got the following results:

"If COND yields non-nil, do BODY, else return nil.
When COND yields non-nil, eval BODY forms sequentially and return

Do these all look OK?  (I'm worried about the first and third.)  I get 
the same results in a build from the (emacs-24) trunk.
