3815 several routines out to avoid deep nesting and indentation.
3816 (Inputs_Match): Add formal parameter Dep_Clause. Rename formal
3817 parameter Do_Checks to Post_Errors. Update the comment on usage.

3992 just direct dependents. If this is actually an abort, each task

3995 time from Vulnerable_Complete_Master "for convenience" (i.e. to
3996 kill off tasks waiting at terminate alternatives), aborting
3997 indirect dependents is wrong, because it causes some unrelated
3998 tasks to get aborted.
