I thought Michael Brand's problem described in

   http://thread.gmane.org/gmane.emacs.orgmode/63523

might have something to do with it, but wrapping a progn around the
forms of the test did not make any difference.

When I simulate the test by hand, I don't get the error, so this seems
to be another of those errors that only surface when the test suite is
run in batch mode.

BTW, why in the above is the following a prog1, rather than a progn?

   (prog1 (goto-line 3) (org-edit-special) (insert "blah") (org-edit-sr
