bug#15722: [PATCH] Man: Add menu.


From: Rüdiger Sonderfeld
Subject: bug#15722: [PATCH] Man: Add menu.
Date: Sat, 26 Oct 2013 14:26:20 +0200
User-agent: KMail/4.11.2 (Linux/3.11.0-12-generic; KDE/4.11.2; x86_64; ; )

I wasn't sure if it is acceptable to use `cl-lib'.  The check whether
there is a "SEE ALSO" section could be simplified to
  (cl-member Man-see-also-regexp Man--sections :test #'string-match-p)

* lisp/man.el (man-imenu-title): New defcustom.
  (Man-mode-map): Add menu entry.
  (Man-mode): Add imenu to menu.
