I was at a pompously titled Software Craftsmanship conference, and one of the questions going around was: "what is the minimum commit size?"
My first guess was one character, since you can fix a bug by changing one character. But in the 'P' vs 'p' case, minimum size could be larger - fixing the calling code is fine, but is there a change that can be made to stop this bug appearing in other calling code? Eg, simplify the interface so that one of the 'p's is protected, so that the wrong Percent can't be set by accident.
