[PATCH] remove will_become_orphaned_pgrp()

Patch from William Lee Irwin III <wli@holomorphy.com>

will_become_orphaned_pgrp()'s sole use is is_orphaned_pgrp().  Fold its body
into is_orphaned_pgrp(), rename __will_become_orphaned_pgrp(), and adjust
callers.  Code shrinkage plus some relief from underscore-itis.
