** m_privmsg
**
** massive cleanup

**
** Another massive cleanup Nov, 2000
** (I don't think there is a single line left from 6/91. Maybe.)
** m_privmsg and m_notice do basically the same thing.
** in the original 2.8.2 code base, they were the same function
** "m_message.c." When we did the great cleanup in conjuncton with bleep
** of ircu fame, we split m_privmsg.c and m_notice.c.
** I don't see the point of that now. Its harder to maintain, its
** easier to introduce bugs into one version and not the other etc.
** Really, the penalty of an extra function call isn't that big a deal folks.
