	* infrun.c (handle_inferior_event): Replace prev_pc test in all
	calls to bpstat_stop_status (removed in 1999-09-24).  This test
	helps distinguish stepping over a breakpoint trap from stepping
	thru a jump to the instruction after a breakpoint trap.
	(handle_inferior_event): Don't bother writing the PC if
	DECR_PC_AFTER_BREAK is zero (optimization).
	* breakpoint.c (bpstat_stop_status): Add comment explaining the
	purpose and usage of the "not_a_breakpoint" argument in computing
	the breakpoint address.
