[PATCH 3(b)/3] _man: Support _correct_word.

[Daniel Shahaf <d.s@daniel.shahaf.name>]

Since compfiles is undocumented, avoid its use altogether, replacing it by
a construct that blackbox analysis suggests to be equivalent.

The compfiles call being removed effected the following change (when
completing «man -S 8:1 getc<TAB>»):

    BEFORE THE CALL:
        typeset -a pages=( /home/daniel/prefix/zsh/share/man/man1/
                           /usr/share/man/man8/
                           /usr/share/man/man1/ )
    AFTER THE CALL:
        typeset -a pages=( '/home/daniel/prefix/zsh/share/man/man1/getc*(8|1)*'
                           '/usr/share/man/man8/getc*(8|1)*'
                           '/usr/share/man/man1/getc*(8|1)*' )

This patch effects the same transformation (modulo doubling the final slash).

Any -M parameter will be passed to compadd.
