Details:


It is useful to search for files that take a lot of disk space. I happen to
have a lot of files that are 1Gbyte large, but occupy only their inode: they
are completely zero. 

I have a cronjob that tries to compress such files. however, compressing
those files that only contain zeroes takes a lot of CPU time, and only
increases the disk usage.

The attached patch implements the -space predicate that checks (like -size)
the size-on-disk instead of the file length.

I'm a technical guy, so I built the patch, but haven't update the docs. Just
drop me a note if you are going to incorporate this and want me to write the
documentation. 

The patch shortens the sourcecode by about 30 lines of code.
