/etc/dump makes bad tape use estimates when files have holes

[Robert Elz]

Thanks for that - dump is one of the programs we didn't get around
to changing to make use of the di_blocks field (whereas 'du', 'ls'
etc, did get changed).

However, that field DOES include indirect blocks - it is used primarily
for the disc quota implementation (so 'chown' can accurately adjust
usages), and as such counts every block that is allocated to the file,
not just data blocks.
