Hammer: df used space output wrong

[Francois Tigeot]

This is the output of df for my /home filesystem:

Filesystem   Size   Used  Avail Capacity  Mounted on
Home         347G   1.0G    78G    77%    /home

The "Used" column is obviously wrong; all other values are about what
they should be.

I recently copied a 40 GB directory on /home which went to 90% capacity.
I later deleted most of the files and kept about only 5GB of them. I then
noticed df(1) output was wrong.

A run of hammer prune didn't fix things; I will run a reblock operation and
report the result later.
