"show directory sizes" gives wrong values - PATCH

Thank you for figuring it out!

I have never heard of the systems where off_t is a double.  off_t is
usually long or "long long".

While at that, I think we should also be concerned about the case when
off_t is unsigned long long, in which case multiplying it by "reverse" (1
or -1) would make no difference.  I've applied a cleaner patch.

Nitpicking: please respect the existing formatting and don't overuse the
"?:" operator if you want your patches to be applied without changes and
under your name.
