I had actually thought a little bit about whether we could put back the
missing output, along the lines of "if it's a syntax-type error and no
error cursor was supplied, assume we should put a cursor at end of input".
It might be worth pursuing if Veillard indicates an unwillingness to
change libxml2 going forward, because a syntax error with no location
can be pretty unfriendly.  But I'll wait to see some response from him
before expending a lot of energy here.

I pushed a set of those an hour ago.  I hope it's just a short-term
hack, but we'll see.  In any case there were now two buildfarm critters
failing, reinforcing the idea that this behavior is spreading.
