[cgiirc-general] PATCH: making links surrounded by <> live

[Jim T. <jt...@on...>]

When presented with a link like <http://example.com/>, CGIIRC  
rel_0_5_9 $ 0_5_CVS $Id: nph-irc.cgi,v 1.120 2006/06/06 18:50:12 dgl   
includes the trailing '>' in the URL and resulting link.

Replacing line 313 of nph-irc.cgi with:
    $line =~ s{((https?|ftp):\/\/[^\004$ ]+)(?![^<]*>)}{$interface- 
 >link(format_remove($1), format_linkshorten($1))}gie;
appears to fix the problem in the typical case, but will fail if the  
URL includes & characters. The trailing '>' has been replaced with  
\004&gt;\004 a couple of lines earlier.

I also suspect the negative lookahead assertion (?![^<]*>) is always  
true since I don't believe there will be any < or > characters by the  
time this regex happens.
