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.
Under some circumstances ngIRCd currently issues a channel MODE message
with a trailing space after the last parameter, which isn't permitted by
the grammar in RFC 2812 section 2.3.1:
http://tools.ietf.org/html/rfc2812#section-2.3.1
The following patch modifies mode-test.e to expose this, and modifies
irc-mode.c to correct it.
