Found it. The vte widget is looking for URLs to highlight, which
means matching against two regular expressions:
(((news|telnet|nttp|file|http|ftp|https)://)|(www|ftp)[-A-Za-z0-9]*\.)[-A-Za-z0-9\.]+(:[0-9]*)?
(((news|telnet|nttp|file|http|ftp|https)://)|(www|ftp)[-A-Za-z0-9]*\.)[-A-Za-z0-9\.]+(:[0-9]*)?/[-A-Za-z0-9_\$\.\+\!\*\(\),;:@&=\?/~\#\%]*[^]'\.}>\) ,\"]
It looks like the Linux native regular expression routines are better
at handling those monsters than the Solaris one is. I've tried
linking gnome-terminal against a couple of old gnu regular expression
libraries and got core dumps; tomorrow I will try pcre (which is more
effort) or just hand-code a matching routine for those particular
URLs.
