Comment out the test of the "opac" record syntax. I feel really

Comment out the test of the "opac" record syntax.  I feel really
terrible about this, because there is a terrible chthonic bug of
ghastly elder-world-invasion proportions, and I _cannot_ find it and
kill it.  All I can tell you right now is that if we don't test for
OPAC records, the bug doesn't happen.  So pragmatism dictates that
right now, we won't check for OPAC records.  But one day, there's
going to be a reckoning.
