This is pretty much ready to land now I think.
I hope to land it tomorrow.

There is a question though re default format to use for cksum -a.
I.e. should we use --tag format by default for cksum -a, as that
is now directly consumable by cksum -c.
If we did that though, we'd have to have the opposite option
for cksum, so something like `cksum --untagged` to produce
the traditional coreutils output format of "$hash  $file".
I'm undecided.
