Yes, I get that, but the else branch of the if did a "diff ? bla /diff : 0"
i.e. only using diff iff it's not zero, while the then branch went about
it another way (i.e. setting diff to 1 if it was zero). I don't like
inconsistencies like that in programs, esp. so close together...
Doing the division only if diff is > 0 saves an assignment and a
division in the case it was zero...
