Nice. I don't have Emacs CVS ;)

Does that break helpex in any way on Emacs-CVS or do you just don't
like having redundant code loaded?

Nicer.

Is there a good solution for the Info-goto-node "problem" as well?
(And, if not, does Info-goto-node work properly w/
partial-completion-mode now? ATM I have quite a dirty hack in my
.emacs for that problem)

IOW: If you have an info file called "foo" with a node "Bar Baz" (e.g.
"(elisp)Regular Expressions"), can you type 

C-h i g (foo)Bar SPC Baz RET 

while p-c-m is enabled, *without* making Emacs barf about no
completion when hitting SPC?

Since you don't have to bind my functions to any key, it should not
make any problems to the "minority" using CVS versions, does it? Or
are the key bindings used by helpex (C-h L, C-h o) used by CVS emacs
by default as well?

BTW: If someone uses CVS, he should be able to rebind the keys to the
"origininal" functions himself...
