Subject: [PATCH] Fix wrong handling of members parameter of RPL_NAMREPLY

Some servers (namely UnrealIRCd) wrongly add a trailing space to the
members parameters of the RPL_NAMREPLY command, which was not handled
correctly.

Adding a trailing space is not legal wrt the IRC specs, but since
UnrealIRCd does it and is in wide use today, we have to work around it.
