commit 53917fa4b80753fc189ed5a516c06c804f2cf415
from: Alexander Barton <alex@barton.de>
date: Sat Nov 10 22:33:19 2012 UTC

Add new IRC+ server flag "X": "XOP modes supported"

This flag indicates, that the server supports the enhanced "xop channel
user modes", like channel owner, admin, and halfop. This information is
used to make sure that no unsupported CHANINFO commands are sent to
servers not supporting such mode prefixes, for example.
