Following is a section of  code from doprint.s in 4.1bsd.  Could
someone explain the 'comet' comment?

__doprnt:
	.word	0xfc0			# uses r11-r6
	movab -256(sp),sp		# work space
	movl 4(ap),r11			# addr of format string
	movl 12(ap),fdesc		# output FILE ptr
	movl 8(ap),ap			# addr of first arg
	clrl nchar				# number of chars transferred
loop:
	movzwl $65535,r0		# pseudo length
	movl r11,r1				# fmt addr
		# comet sucks.
	movq *fdesc,r4
	subl3 r1,r5,r2
	jlss lp1
	.
