[gentoo-dev] [PATCH v2] texlive-module.eclass: install man pages in right location

[Florian Schmaus <flow@gentoo.org>]

The TeX Live packages under dev-texlive/* currently do not install the
man pages in the right location. They are under
/usr/share/texmf-dist/doc/man.

Install them at the right location using doman.

Having dev-texlive/* packages installing man pages requires that we
filter man pages already installed by app-text/texlive-core to avoid
file collisions. As a consequence, unfortunately, we have to hard code
the list of man pages installed by texlive-core. Or, at least, folks
from #-tex and myself could not come up with a solution that does not
require hard coding that list.
