Ulrich,
This is not something that groff agrees upon. The stock groff on
GNU/Linux returns `n' instead of `pi'. Version: GNU troff (groff)
version 1.21. We've discussed this before, I think... the quick
solution is to patch it downstream (chars.in). I personally don't like
the attenuation of /any/ Greek characters, as my own formulas end up
confusing (those with both pi and n, for example).
