BUG:	CONVOLVE was terminating with the error 'Kernel rows are different
	lengths' if the user supplied a 1D kernel without the terminating
	delimiter character ';'. For example the valid kernel '1.0 2.0 1.0;'
	would work but the equally valid '1.0 2.0 1.0' would not. 2D kernels
	did not have this problem.

STATUS:	The bug is fixed in IRAF 2.10. The workaround is to always append
	the delimiter character to the kernel.
