Bug#164889: md5sum <FILE produces spurious ` -' in output

[Ian Jackson <ian@davenant.greenend.org.uk>]

The Technical Committee has decided:
> 11. We [require] that the package maintainer indicate
>     whether they would prefer the bug submitter to prepare a patch.
>     If so then when the submitter has prepared a reasonable patch, the
>     maintainer should accept and apply it if they approve; otherwise,
>     or if they prefer, they should do the necessary work themselves.

Please advise.

Ian.
