Seams sensible. I mostly use the -B option (block size 5120 bytes) but
I've also tried without (i.e. 512 bytes). Regular cpio doesn't seem to
care when reading, what option was used to create the archive.

ISTR that maybe the defualt block size should be be 512.

I'm happy to test out any patches etc.
