	* s-taskin.ads: Minor comment fix.
	* s-tassta.adb (Abort_Dependents): Don't abort all dependents;
	just direct dependents. If this is actually an abort, each task
	will take care of aborting its dependents, so all dependents will
	get aborted, as before. However, when this is called the second
	time from Vulnerable_Complete_Master "for convenience" (i.e. to
	kill off tasks waiting at terminate alternatives), aborting
	indirect dependents is wrong, because it causes some unrelated
	tasks to get aborted.
