lib/texinputs/isabelle.sty

simplified interface to define document antiquotations, cf. antiquotatation, maybe_pretty_source, output;
removed incomprehensible args parser setup;
removed obsolete locale flag -- text is already localized;
misc tuning and cleanup of concrete antiquotations;
goal state antiquotations: ignore source flag;

%% macros for Isabelle generated LaTeX output

%%% Simple document preparation (based on theory token language and symbols)
