[patch] bb-findhost.cgi redirects to the page when only one host matches

[Charles Goyard]

hi,

I made a small modification to bb-findhost.c so that when a search
yields only one results, you get transported to that page.

Since we only know there's one result after a full scan of the bb-hosts
file, and don't want to scan the file twice, I use an ugly way to do it:
a javascript redirect held in a <img> tag.

This works for 4.1.2p1, but the patch applies in 4.2-beta-20060605 too (not
tested live, thought).


Regards,
