I'm attaching the patch I desired.  Please review.  This will probably miss
this week's minor releases.  If there's significant support, I could instead
push before the wrap.

Commits

  1. Ignore XML declaration in xpath_internal(), for UTF8 databases.

  2. Add warning that xpath() doesn't work with non-UTF8 data.
