Yep.

Heh, I've been thinking about special-casing the common case even before
you've proposed it, but thanks anyway!  ;-)

It's more that I wanted to wait at least until we have the machinery in
place for non-transformed manpages (which it is now), so special-casing
can be done for both at the same time.  Since you've beaten me now with
a patch, I'll instead look at it now.
