Log:
  bin/dd: Fix incorrect casting of arguments

  dd(1) casts many of its numeric arguments from uintmax_t to intmax_t
  and back again to detect whether or not the original arguments were
  negative. This caused wrong behaviour in some boundary cases:

  $ dd if=/dev/zero of=/dev/null count=18446744073709551615
  dd: count cannot be negative

  After the fix:

  $ dd if=/dev/zero of=/dev/null count=18446744073709551615
  dd: count: Result too large
