Added tag Isabelle2014-RC1 for changeset c0fd03d13d28
some actual workaround to remove document nodes;
do not embed 'nat' into 'int's in 'smt2' method -- this is highly inefficient and decreases the Sledgehammer success rate significantly
made tactic more robust w.r.t. dead variables; tuned;
better ordering of positive_integral renaming to nn_integral in NEWS
NEWS
CONTRIBUTORS;
add Isabelle Datatype Manual to the bibliography
update documentation for Lifting/Transfer
correctly resolve selector names in default value equations
more general notion of "user error" including empty message -- NB: Output.error_message needs non-empty string to emit anything;
clarified compile-time use of ML_print_depth;
completion popup supports both ENTER and TAB (default);
prefer dynamic ML_print_depth if context happens to be available;
more keyword categories (as in ML);
agree on keyword categories with ML;
removed unused stuff;
careful when calling 'Thm.proof_body_of' -- it can throw exceptions
prefer non-strict Execution.print, e.g relevant for redirected ML compiler reports after error (see also e79f76a48449 and 40274e4f5ebf);
tuned output;
