They fail in both modes. The way the test cases are written which
I'm modifying makes it rather ugly to insert AT&T tests. If you
want to really force me to do that juggling, may I please ask that
on _all_ future tests, line number and section offsets should either
be expressed by regex-es or, should their checking be a requirement
(like is the case here), Intel and AT&T syntax inputs go into different
files so one can easily add to the end of a file without having to flip
flop between syntaxes?

Please clarify your expectations.
