No other IRC daemon seems to do this (today?), don't remember why
ngIRCd did it in the first place ...
Closes#185.
Reported by Cahata in #ngircd, thanks!
Different operating systems do behave quite differently when doing DNS
lookups, for example "127.0.0.1" sometimes resolves to "localhost" and
sometimes to "localhost.localdomain" (for example OpenBSD). And other
systems resolve "localhost" to the real host name (for example Cygwin).
So not using DNS at all makes the test site much more portable.
The students in my software-engineering class are writing IRC clients in
Java, and I'm running ngIRCd as a sandbox for them to play in. We
noticed ngIRCd doesn't obey the "JOIN 0" command specified in RFC 2812:
JOIN 0 ; Leave all currently joined
channels.

I believe the following patch addresses this. Cheers!
[fw@strlen.de: put it into a seperate function]
