dest: sort strings; report: Output.status;

added literal;

read_token: more robust handling of empty text;

datatype token: maintain range, tuned representation; moved eof, stopper to lexicon.ML;

datatype token: maintain range, tuned representation; tuned messages;

datatype token: maintain range, tuned representation; added eof, stopper (from simple_parse.ML); str_of_token: no special case for EOF; misc tuning;

tuned SymbolPos interface;

YXML.parse: allow text without markup, potentially empty;

added lemmas

inner_syntax markup is back;

disabled inner_syntax markup for now;
