Corrected an error caused by a recent commit that was attempting

to avoid bogus values for array pitch in the direction in which
a cell is not arrayed:  If the array declares an ANGLE of 90 or
270, then rows and columns are effectively swapped for the
purpose of figuring out which coordinate direction should be
ignored in the input.  The original example did not use ANGLE
and so the exception was not handled.
