commit cd38e9580e428103cef39e2e29f62472b2f336d3
from: Federico G. Schwindt <fgsch@lodoss.net>
date: Sun Aug 11 19:57:11 2013 UTC

Fix 2 bugs introduced in 74514b8c23

Channel_Modes() and Channel_Topic() return static memory that is zeroed at
creation time. Fix checking for empty modes and topic so they're propagated
correctly.
