Revision:	357
Committed:	Thu Jan 5 16:06:45 2006 UTC (20 years, 7 months ago) by michael
Content type:	text/x-csrc
File size:	7801 byte(s)
Log Message:	- Mainly re-wrote split_nuh() to fix a regexp kline bug where we would cut off the user portion after 9 chars, but also to be a bit more flexible when we have to deal with different user/host name lengths. - Re-wrote m_capture() to use split_nuh()
