I'm guessing you're testing for whether the remote user is listed in
sudoers with a "NO-PASSWORD" type setting? Can't fathom what else it
might be where sudo works well enough to spit out a prompt but is
otherwise incorrectly configured :)

If that's accurate, I would imagine this is indeed a bit of an edge
case -- I'd feel kind of funny about putting in a config setting to
the effect of "if sudo appears to be working correctly, don't prompt
me, send up an abort/warn instead".

You could pretty easily modify your local copy of fabric/network.py,
line 305, so that the top of the "if initial or try_again:" block
calls warn() or abort(). That should, I think, do what you need.

Best,
