Hi Guenter,

I was on the fence...

Typically we say if you can do it easily via a script,
there's no need for the feature or change.  But this change
is so small and for a format so close to the existing format --
and there are no restrictions from the likes of POSIX, which
doesn't specify how conforming md5sum, sha*sum work --
that improved usability is a good enough argument.

Would you like to write the patch (including NEWS and
a small doc update), following these guidelines?
