After seeing too many "case 1", "case 2", "case 3" and corresponding facts "1", "2", "3" I've now pushed this trivial change through, really with rare incompatibilities.
Here is an example changeset that illustrates the reduction of odd digits and redundancy in the source, for better proof mainainability: http://isabelle.in.tum.de/repos/isabelle/rev/19c277ea65ae
I had already adapted these theories from HOL-Library and HOL-Decision_Procs earlier, to make use of 'consider' and statements with 'if' / 'for'. Thus raw proof blocks with big-bang integration by blast are mostly eliminated, and replaced by explicit proof structure.
