bug#30785: Man pages truncated, repeated

[Danny Milosavljevic]

Correction, the file "charset.alias" is only installed for groff for glibc < 
2.1 .
The code that reads charset.alias is always created.
What could possibly go wrong?

Anyway, I suggest the following minimal patch:

diff --git a/gnu/packages/groff.scm b/gnu/packages/groff.scm
