Theorems symmetric, reflexive and transitive are now stored with "open" derivations.

Commands prf and full_prf can now also be used to display proof term of current proof state.

* Isar/Pure: emulation of instantiation tactics (rule_tac, cut_tac, etc.) now consider the syntactic context of assumptions, giving a better chance to get type-inference of the arguments right (this is especially important for locales); * system: refrain from any attempt at filtering input streams; no longer support ``8bit'' encoding of old isabelle font, instead proper iso-latin characters may now be used;

* Isar/Pure: proper integration with ``locales''; unlike the original version by Florian Kammueller, Isar locales package high-level proof contexts rather than raw logical ones (e.g. we admit to include attributes everywhere); * Isar/Pure: theory goals now support ad-hoc contexts, which are discharged in the result, as in ``lemma (assumes A and B) K: A .''; syntax coincides with that of a locale body;
