I never meant to make it equivalent. I meant to revert the behavior as
the previous cset, keeping the core of the fix contained in the buggy
cset :-)

To sum up thing, "a++" is a postfixed operation, it's evaluated after the use
of "a" whereas "a +=" is a prefixed operation, a is first evaluated and
then used.

We all agree on that :-) At least, that's what my dusty C book tells me.
