After thinking about the patch a bit more, let's omit the part about 
adding new conversions iseek_bytes etc., as I think there's a better way 
to address that issue. I proposed something in <https://bugs.gnu.org/54112>.

So instead of your patch, I installed the attached patches. The first 
one adds the iseek and oseek operands that you suggested; the second one 
clarifies dd documentation, as I found several things were confusing 
when rereading it carefully. Something like these patches should appear 
in the next coreutils release.
