My first conclusion was wrong.  "back" gets me the right buffer but it
gives me different contents.  After C-h b my first 12 lines of the
*Help* buffer are


Key translations:
key             binding
---             -------

C-x		Prefix Command
<double-down-mouse-1> mouse--down-1-maybe-follows-link
<down-mouse-1>	mouse--down-1-maybe-follows-link

C-x 8		iso-transl-ctl-x-8-map

C-x 8 SPC	
...


and *Help* has 1050 lines while after going to some function and hitting
"back" these lines are


Key translations:
key             binding
---             -------

C-x		Prefix Command
A-SPC		
A-!		¡
A-"		Prefix Command
A-$		¤
A-'		Prefix Command
A-*		Prefix Command
A-+		±
...


and *Help* has 1637 lines.  Confusing.  I think I'll have to debug
`describe-buffer-bindings' to find out what happens.
