3erl here means that only manpages in 3erl subsection will be
searched. Which makes the most important section correct. Emacs shows
only Erlang-related manpages for section 3.

It's a policy rule to put manpages under /usr/share/man (it's
convenient to use 'man' for all manpages and don't try to remember
when you should type 'man' and when 'erl -man' whatever.

Which isn't too problematic as there are not too many manpages in
sections 4 and 6. Only section 1 contains many manuals.

The regexp is correct.

It seems to be too complicated for me. While I agree that the change
introduced in the Debian package creates some inconvenience for Emacs
user I think that it isn't too annoying to excuse symlinking.
