o Add a ``-o'' argument to initattr, which causes extattrctl to overwrite
the existing attribute file rather than aborting with an error.
o Useful if you want to reset the state of attributes on the system without
allocating different disk blocks through deletion and recreation,
for example, if you're doing benchmarks of extended attribute code. :-)
