tuned signature;

optional 'includes' element for long theorem statements; tuned signatures;

basic support for nested contexts including bundles; include multiple bundles; renamed "affirm" back to "assert" (cf. c4492c6bf450 which was motivated by obsolete Alice/ML); tuned signatures;

tuned messages;

basic support for nested local theory targets;

try apple.laf.useScreenMenuBar=false to make menus stay closer to the editor views they belong to -- potentially less confusing for jEdit newcomers;

improved isatest arguments for macbroy2;

prefer explicitly qualified exception List.Empty;

merged

basic support for bundled declarations;
