140 | ** (I don't think there is a single line left from 6/91. Maybe.) | |
141 | ** m_privmsg and m_notice do basically the same thing. | |
142 | ** in the original 2.8.2 code base, they were the same function | |
143 | ** "m_message.c." When we did the great cleanup in conjuncton with bleep | |
144 | ** of ircu fame, we split m_privmsg.c and m_notice.c. | |
145 | ** I don't see the point of that now. Its harder to maintain, its | |
