For reference, that's

I admit that patch is very ugly indeed.

The following works for our special purposes, seems less intrusive,
and allows to drop the fiddling with env.cpp.

Do you agree that's an improvement?

(No doubt it's still somewhat ugly, but it is needed to make sure
 that all manuals look similar in style, and even more to allow
 automated output comparisons, to avoid that mandoc drifts away
 from groff regarding details of output formatting.
 And at least people can easily disable these manipulations
 when they want to do serious publishing work with groff.)

Of course, this is not useful upstream or on other platforms,
i'm just trying to minimize our local tweaks right now.

Thanks,
  Ingo
