[erlang-bugs] Building docs for R13B-03 fails

Hi again!

It seems that XSLT stylesheets which were used to generate Erlang
R13B03 manpages are a bit buggy. The main problem is that in the
generated manpages lines often start with dot (.) or apostrophe (').
These characters start groff macros, so some info will be lost after
manpage formatting.

Also, tools like apropos don't understand the APPLICATION or MODULE
sections and try to find the NAME one.

Another minor bug is incorrect authors information formatting.

The attached patch simply makes xsltproc add \& before all dot and
apostrophe symbols, and replaces MODULE by NAME header, and adds some
authors processing.

To check for bugs the following command can be used:
LANG=C MANWIDTH=80 man --warnings -l filename.3 >/dev/null
