Let count=-something fail, while count=0 may succeed, thus making dd(1)
useful as a seeking-tool as well as its many other uses. Previously,
dd(1) would succeed with count=0, but wouldn't get to the point that
blocks were to be read/written. This is a more useful behavior, and
this specific case doesn't seem to be handled by POSIX.
