This is a good suggestion; thanks.
dd could support 'dd bs=0xe0000' as a pure extension to POSIX, since
POSIX requires that the operands of 'x' must be positive. However,
that's pretty flaky, and I'd rather not do that. (Try parsing "dd
bs=0xe0000x10x0x10" in your head. :-)
Given that a POSIX shell has an easy way to address this issue,
perhaps we should just leave things be.
