I assumed that much.  Just letting you know.

It doesn't break anything, but you might want to only use your definition if
the underlying Emacs does not offer its own (unless yours has some extra
feature, of course).

IIRC, the goto-node code in CVS does completion within the parenthesese,
but it does not do completion of the node name afterwards (this requires
looking inside the Info file and I didn't bother writing it up).

I haven't used p-c-m in a while and I use C-a SPC to insert a space, so
I wouldn't know.  If it works without p-c-m, then it's a bug in p-c-m,
otherwise it's a misfeature.

Oh, no, as I said, there's no problem whatsoever.  I was just advocating my
own code, hoping you'd try it out and improve it further rather than just
replicate it in your own corner with just slightly different limitations.
