more explicit error message; convert/revert range; tuned;

merged

gave up an optimization that sometimes lead to unsound proofs -- in short, facts talking about a schematic type variable can encode a cardinality constraint and be consistent with HOL, e.g. "card (UNIV::?'a set) = 1 ==> ALL x y. x = y"

added missing case in pattern matching -- solves Waldmeister "Match" exceptions that have been plaguing some users

fixed soundness bug related to extensionality

unconditional recovery from bad context (e.g. Quoted with malformed quoted_body);

flush snapshot on falling edge of is_outdated -- recover effect of former buffer.propertiesChanged on text area (cf. f0770743b7ec);

recovered markup for non-alphabetic keywords;

more precise imitation of original TextAreaPainter: no locking;

more precise imitatation of original TokenMarker: no locking, interned context etc.;

brute-force range restriction to avoid spurious crashes;

static token markup, based on outer syntax only; eliminated obsolete buffer.propertiesChanged (expensive due to remarking of full buffer etc.);

explicit dependency on Pure.jar;

partial scans of nested comments;

some support for partial scans with explicit context; clarified junk vs. junk1;

tuned spelling

updated generated file;

avoid compiler warning -- this is unchecked anyway;

fixed soundness bug made more visible by previous change

use more appropriate type systems for ATP exporter

type arguments now (unlike back when fa2cf11d6351 was done) normally carry enough information to reconstruct the type of an applied constant, so no need to constraint the argument types in those cases

more robust painter_body wrt. EBP races and spurious exceptions (which causes jEdit to remove the extension);

more robust init;

recovered orig_text_painter from f4141da52e92;
