Subject: [htdig3-dev] url_seed_score patch for htdig-3.1.4

Please note that I'll update and check in this patch to the main
trunk as soon as the merges from 3.2.0 are finished.  If it is
requested, I could check it into the htdig-3-1-x branch too.
 Not for 3.2.0.

I send it here as a heads-up, for the benefit of peer review, and
for bleeding-edge patch archives (hey, I *did* test it).

For prospective users: If you want to just order your search results in
areas, you may want to wait for a patch to implement an attribute
"results_order".
