repaired logic for default provers -- ensures Z3 is kept if installed and configured as noncommercial

avoid changing the state's context -- this results in transfer problems later with SMT, and hence preplay tactic failures

removed hint that is seldom useful in practice

reactivate some examples that still appear to work;

removed dead code;

explicit indication that redefining outer syntax commands is not supposed to happen -- NB: interactive mode requires global change of syntax;

do not redefine outer syntax commands;

tuned whitespace;

static repair of ML file -- untested (!) by default since 76965c356d2a;

iteration n in the 'default' vs. 'update_new' vs. 'update' saga -- 'update' makes sense now that we honor the canonical order on 'merge' (as opposed to raising 'DUP')

don't hide constant forever, since it may appear in some 'primcorec'-generated theorems

tuning

HOL-IMP fastness

merged, resolving some conflicts;

eliminated hard tabs (assuming tab-width=2);

more platform notes;

tuned whitespace;

removed odd comments -- inferred types are shown by Prover IDE;

maintain blob edits within history, which is important for Snapshot.convert/revert;

more accurate eq_content;

clarified message_positions: cover alt_id as well; tuned;

maintain multiple command chunks and markup trees: for main chunk and loaded files; document view for all text areas, including auxiliary files;

common Command.Chunk for command source and auxiliary files (static Symbol.Index without actual String content); more informative type Blob, to allow markup reports;

tuned signature;

report (but ignore) markup within auxiliary files;

merged

make integer_of_char and char_of_integer work with NBE and code_simp

make lifting setup for String.literal local to prevent transfer from replacing STR ''...'' literals
