support bulk messages consisting of small string segments, which are more healthy to the Poly/ML RTS and might prevent spurious GC crashes such as MTGCProcessMarkPointers::ScanAddressesInObject;
some shortcuts for chunks, which sometimes avoid bulky string output;
store blob content within document node: aux. files that were once open are made persistent;
proper structural equality for Command.File and Symbol.Index;
tuned signature -- more static typing;
tuned output;
tuned proofs
proper structural hashCode, which is required for Command.File equals (NB: Array has physical object identity);
reset mouse pointer more decisively, for the sake of Mac OS X (despite the builtin policie of jEdit);
clear active areas (notably mouse pointer) before changing context (e.g. via hyperlink);
observe focus change for all tooltips, e.g. relevant for focus change to unrelated components;
cumulative NEWS;
