--- Comment #2 from rittneje+bugzilla at gmail.com ---
Particularly with a Dockerfile, people are not always literally feeding the
output of sha256sum to itself. It's pretty common to hand-write the echo
instead. And the double space is very easy to overlook.

As I mentioned, this is particularly confusing because (1) no other
implementation of sha256sum cares, and (2) this implementation never clearly
states what the problem is. Consequently people come to the conclusion that it
is broken.
