I think this should fail.

I've long thought that ideally giving anything but a single good rev to
"rev-parse --verify" should fail before spitting anything out.  This, like
other reponses to errorneous inputs, were what we considered of lower
priority in early days of git (think "before the end of 2005"), because we
had many other "better and more urgent" things to worry about.  I think we
have long passed that stage.
