Regarding this one.
I saw this support request http://drupal.org/node/30845 and I wonder if we
shouldn't correct this at least in drupal.module as it's not a Drupal.org
related bug.

Also, all drupal is parsed wih www.drupal.org weblinks. There's no problem
having these as browser will follow the redirect without noticing it. But
XML-RPC won't and generate a warning in watchdog, so I think it worth moving
it back to drupal.module and make a little patch (done) to change the
default setting.

But what about URLs in Drupal ? Should we let them as is, or change them all
to drupal.org ?
