Subject: [PATCH] irc: fix buffer switching on manual join for forwarded
 channels

Previously using option values
	irc.look.buffer_open_before_join off
	irc.look.buffer_switch_join on
and manually joining a channel which gets forwarded
(e.g. #linux -> ##linux-overflow on freenode) the channel buffer for
##linux-overflow was not switched to even though the option says it should
have.

This patch copies manual join and noswitch information for channels which
get forwarded.
