I'm not at all sure this is clearer than the goto-full version. You have taken
a single logical operation and split it in two parts. If you consider the goto
the work of the devil, then of course this represents progress. If you don't,
but consider it a rather esoteric tool to be used for unusual circumstances,
then it doesn't.

Consider that it's now less maintainable, since you have the same set of cases
included in two places. What happens if you put in a '%b' format? Now you
have two places to add the code for printing in binary.

Personally, I find gotos not a lot diffreent from switches and return
statements, and a lot less confusing than longjmp.
