[IRCServices] JOIN 0 subject

[Andrew Kempe]

I will fix this problem soon. Removing support for /JOIN 0 from the ircd
source is just not a viable option. There are far too many ircd variants out
there, and this is legacy code. We just have to go with the flow. Besides,
it's not that hard to implement.
