Subject: erlang-mode,
 erlang-manpages: non erlang related manpages in the "Erlang" menu at the

Package: erlang-mode
Version: 1:13.b.2.1-dfsg-1
Severity: normal


erlang-mode builds the manpage menus by searching for manpages in the directory specified
using the erlang-root-dir variable setted to "/usr/lib/erlang" in 
/etc/emacs/site-start.d/50erlang-mode.el, and the erlang-man-dirs variable setted on
erlang-mode.el. Then uses a regex defined in erlang-mode.el as:

  (defun erlang-man-get-files (dir)
    "Return files in directory DIR."
    (directory-files dir t ".*\\.\\([124-9]\\|3erl\\)?\\(\\.gz\\)?\\'"))

The erlang-manpages package installs the manpages on /usr/share/man/* where non erlang
related manpages also reside, and creates a /usr/lib/erlang/man -> /usr/share/man symlink.

So, by traversing that symlink erlang-mode erroneously founds all manpages in the system as
erlang ones. 

Two notes about the regex: 1- there are other similar regexes used in
erlang-mode.el 2- the "3erl" string must be optional because there are manpages like
/usr/share/man/man6/kernel.6.gz that not contain it.  

I think the proper solution is to modify erlang-manpages to create an 
/usr/lib/erlang/man directory instead of a symlink, and then man{3,4,6} directories
containing  one symlink for each manpage to his corresponding file in /usr/share/man 
(or viceversa).

Btw, this seems to be the continuation of the #436044 bug :) Creating the /usr/lib/erlang/man
was a bad solution, erlang manpages become undifferentiated, but the empty /usr/lib/erlang/man
was also bad.
