31 1.1:-
32 * added changes from Miles Bader-
33 * corrected a bug with %f-
34 * added support for %#g-
35 * added more comments :-)-
36 1.0:-
37 * supporting must ANSI syntaxic_sugars-
38 0.0:-
39 * support %s %c %d-

50 * Currently doesn't handle (and bash/readline doesn't use):-
51 * * *M$ width, precision specifications-
52 * * %N$ numbered argument conversions-
53 * * support for `F' is imperfect with ldfallback(), since underlying-
54 * printf may not handle it -- should ideally have another autoconf test-
