cursory polishing: tuned proofs, tuned symbols, tuned headings
earlier setup of transfer, without dependency on psychodelic interpretations
tuned signature -- more explicit Document.Elements;
more symbols, less parentheses;
incorporate chunk range that is 1 off end-of-input, for improved error positions (NB: command spans are tight, without trailing whitespace);
tuned signature;
font size change with delay, to avoid GUI lagging behind user input;
more precise imports;
avoid duplicated simp rules in fact collections;
dropped redundancy
tuned;
tuned signature -- separate module Font_Info;
tuned;
clarified module structure;
made SML/NJ happier
clarified language markup: added "delimited" property;
type Symbol_Pos.source preserves information about delimited outer tokens (e.g string, cartouche);
observe Completion.Language_Context only for delimited languages, which is important to complete keywords after undelimited inner tokens, e.g. "lemma A pro";
