I'm sorry, then. I must be misremembering that.

Oh, heck.

:-(  Yeah. My whole report only makes sense if ctl-H ctl-A is supposed to
get you to apropos.  I didn't try to reproduce the problem because I was 
afraid I'd be bumped out of the bug report window, so I was working from 
memory. And since I'd been looking for apropos, I took "information 
about GNU Emacs and the GNU system" as being a description of
apropos, which is only true in the most general sense. 

Summary: Ow, sorry for wasting your time.
