Toplevel.run_command: reraise Interrupt, to terminate the Isar_Document.execution and not store a failed attempt;

Typo in locales tutorial.

Theory_Target.pretty: more markup;

tuned abbrevs for long arrows, according to usual ASCII syntax;

more flexibile font size via CSS <style> instead of old <font> element; preformatted text;

tuned;

control tooltip font via Swing HTML, with tooltip-font-size property;

added HTML.encode (in Scala), similar to HTML.output in ML;

one extra space to accomodate symbolic indentifiers etc.;

replaced ML_Lex.read_antiq by more concise ML_Lex.read, which includes full read/report with explicit position information; ML_Context.eval/expression expect explicit ML_Lex source, which allows surrounding further text without loosing position information; fall back on ML_Context.eval_text if there is no position or no surrounding text; proper Args.name_source_position for method "tactic" and "raw_tactic"; tuned;

more detailed token markup, including command kind as sub_kind; type-safe access to Command.HighlightInfo;

tuned;

separate markup for ML delimiters;

less pschedelic token markup;

simplified command/keyword markup;

markup non-identifier keyword as operator;

Isabelle_Process: do not enforce future_terminal_proof by default -- no error propagation yet;

more basic default behaviour of ENTER, HOME, END;

tuned messages;

do not highlight ignored command spans; tuned;

more explicit handling of document;

explicit markup for forked goals, as indicated by Goal.fork; accumulate pending forks within command state and hilight accordingly; Isabelle_Process: enforce future_terminal_proof, which gives some impression of non-linear/parallel checking;

avoid :\ which is not tail-recursive and tends to overflow the tiny JVM stack, which is not resizable at runtime;

define_state/new_state: provide state immediately, which is now lazy; more careful document editing: single execution future forces all entries, synchronous cancelation after update;

force_result within the current execution context -- avoids overhead of potential thread context switch and robustifies Interrupt handling; recovered some similarity to sequential version;

future result: retain plain Interrupt for vacuous group exceptions;

remove two examples, now that the definition of "fst" and "snd" has changed
