src/Pure/ProofGeneral/pgip_tests.ML

proper subgoal addressing via SUBGOAL/CSUBGOAL -- assuming these tactics did not handle Subscript in any special way;
tuned;

(*  Title:      Pure/ProofGeneral/pgip_tests.ML
    Author:     David Aspinall

A test suite for the PGIP abstraction code (in progress).
Run to provide some mild insurance against breakage in Isabelle here.
