Join forwarding can appear very unfriendly in certain cases

[dmlloyd]

This problem was observed in ircd-seven on FreeNode but it was recommended to bring it here.

If you (as a user/channel owner, not IRC oper) have a channel forward set up from some channel to another, via a +f in combination with a +i or widely-applying +b or whatever, then in most clients (by now anyway) you are forwarded without a problem. However if you happen to already be in the target channel, you are presented with an often-hostile message corresponding to the +i or +b or whatever mechanism you used to block access to the original channel.

For people who are not really familiar with IRC (and in fact for some who are), this behavior is pretty scary/off-putting. It would be nicer perhaps if the server always responded with the 470 "ERR_LINKCHANNEL" code in this case - or at the least, there should be a way to enable this behavior.

I agree that the current behaviour is suboptimal.

i agree with the change but don't really know of a good way to do it cleanly.
