The tech-ctte had ruled some time ago that md5sum from stdin should not

It's that way in sarge also. I'm frankly going to ignore this unless the
tech ctte revisits it. AFAICT this was dealt with in the tech ctte because
it was a pet peeve of ian jackson. I find it vaguely disturbing that
there was an entire thread about changing the behavior of a program in
coreutils that *was never mentioned to the coreutils maintainer*. Since
nobody told me about this discussion, I'll assume I was meant to ignore
it. FWIW, both md5sums in sarge shipped with the "forbidden" behavior
and I see no compelling reason whatsoever to deviate from either our own
current output or every other distribution's (which is based on
coreutils' upstream behavior).
