farewell to old-style mem infixes -- type inference in situations with mem_int and mem_string should provide enough information to resolve the type of (op =)

constant name access lattice is not in use any longer

uniform treatment of length = 1 for forced breaks, also makes ML/Pretty.length coincide with Scala/XML.content_length;

basic formatting of pretty trees; line-up ML vs. Scala sources;

added content_length;

slightly more general Library.chunks;

misc tuning -- accumulate body via ListBuffer;

basic support for symbolic pretty printing; tuned;

extractors for document updates; Session.handle_result: use extractors instead of raw patterns -- NB: using mixed patterns of case classes vs. extractors crashes Scala 2.8.1 RC1;

extractors for outer keyword declarations;

eliminated deprecated "--" method; use case classes with copy method for functional record update;

use IndexedSeq instead of deprecated RandomAccessSeq, which is merely an alias;

use SwingApplication instead of deprecated GUIApplication;

proof terms for strip_shyps, based on the version by krauss/schropp with some notable differences: * present type variables are only compared wrt. first component (the atomic type), not the duplicated sort; * extra sorts are grounded towards fixed 'a, potentially with different sorts (the original version with Name.names could cause name clashes with other present variables, too, but this should not be a problem); * deriv_rule_unconditional ensures that proof terms are always maintained independently of the "proofs" flag -- this improves robustness and preserves basic PThm proofs required for extraction attributes, e.g. in theory HOL/Extraction;

simplified/unified fundamental operations on types/terms/proofterms -- prefer Same.operation over "option" variant;

renamed Proofterm.freezeT to Proofterm.legacy_freezeT (cf. 88756a5a92fc);

specification goal: eliminated redundant Thm.legacy_freezeT -- the goal is properly declared and should always produce fixed types in the result; specification result: replaced Thm.legacy_freezeT by Thm.unvarify_global -- the final result appears to be a closed term that is globally exported;

UNDISCH/DISJ_CASESL: eliminated slightly odd Thm.legacy_freezeT -- these rules appear to be applied to thms with fixed types only;

replaced Thm.legacy_freezeT by Thm.unvarify_global -- these facts stem from closed definitions, i.e. there are no term Vars;
