Pull up following revision(s) (requested by gutteridge in ticket #1433):

        usr.bin/man/man.c: revision 1.69
        usr.bin/man/man.c: revision 1.70
        usr.bin/man/man.c: revision 1.72

man.c: fix -m option so it works as documented

Refactoring work in man.c r. 1.40 from twelve years ago introduced a
regression where input from the -m option was appended rather than
prepended to the search paths. Problem reported by C. Chapman on
netbsd-users.

man: fix type mismatch between enum and int (since yesterday)
No binary change.

man: remove unused global variable 'instype' (since yesterday)
No functional change.
