clarified specific use of inspect_contract: "any Bound variable will do" may render the term invalid for Term.fastype_of1 in inst_subst_tac (see also 7c3757fccf0e);

tuned whitespace;

tuned ML signature (and rationalized code a bit)

merged

case_of_simps: do not split for types with a single constructor

tests for Simps_Case_Conv

merged

clarified context; eliminated dead code;

clarified context;

Variable.focus etc.: optional bindings provided by user; Subgoal.focus command: more careful treatment of user-provided bindings;

clarified text folds: proof ... qed counts as extra block;

more accurate skip_proofs nesting, e.g. relevant for 'subgoal' command;

tuned according to a81dc82ecba3;

tuned facts

more cautious use of [iff] declarations

avoid explicit definition of the relation of associated elements in a ring -- prefer explicit normalization instead
