pf.conf manpage addition

[Attila Nagy <bra@fsn.hu>]

Hello,

pf.conf(5) says:
     rule       = action ( "in" | "out" )
                  [ "log" | "log-all" ] [ "quick" ]
                  [ "on" interface-name ] [ route ] [ af ]

Which isn't really true (I think :), because interface-name can be
interface-list too (at least in -current).
I can use "pass in on { $if_dmz0, if_dmz1 } ..." which is expanded to
"pass in on xl0 ..."
"pass in on xl1 ..."
correctly.

I think this should be noted in the manpage.

Thanks,
