138 ** (I don't think there is a single line left from 6/91. Maybe.)
139 ** m_privmsg and m_notice do basically the same thing.
140 ** in the original 2.8.2 code base, they were the same function
141 ** "m_message.c." When we did the great cleanup in conjuncton with bleep
142 ** of ircu fame, we split m_privmsg.c and m_notice.c.
143 ** I don't see the point of that now. Its harder to maintain, its
144 ** easier to introduce bugs into one version and not the other etc.
145 ** Really, the penalty of an extra function call isn't that big a deal folks.
