-A Display the apparent size instead of the disk usage. This can be
helpful when operating on compressed volumes or sparse files.
-B blocksize
Calculate block counts in blocksize byte blocks. This is differ-
ent from the -k, -m options or setting BLOCKSIZE and gives an
estimate of how much space the examined file hierachy would
require on a filesystem with the given blocksize. Unless in -A
mode, blocksize is rounded up to the next multiple of 512.
The former is similar to GNU's du(1) --apparent-size. The latter is
different from what GNU's du(1) -B does, which is equivalent to setting
BLOCKSIZE in our implementation and is rather pointless as it doesn't add
any real value (i.e. you can achieve the same with a simple awk-script).
No change in the normal output or processing.

of the GNU utility. The default behavior of our original `du' is to
count hardlinked files only once for each invocation of the utility.
With the new -l option they count towards the final size every time
they are found.

* re-word parts of the man page which I felt were badly worded
or ambiguous.
* change the behaviour of argument processing so that when more
than one of the -P, -H and -L options are specified it will
print an error message, rather than choosing the last option
specified, this behaviour is more logical and consistent with
other utilities.
* change the behaviour of argument processing so that negative
arguments to the -d option are not allowed.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
