As a bit of shameless self-promotion, I use my man-completion.el
... http://user42.tuxfamily.org/man-completion/index.html

Among its feeping creatures it tries to cope with pages the same name in
different sections, long names truncated to the tty width, a cache
because man -k takes a couple of seconds for me, and filenames for M-x
man "-l foo".
