The output may look like the above, but people would certainly wish
to clarify and/or translate "from '%s'" part.  And to allow that, we
may need to signal a bit more explicitly that we saw a non-symref
HEAD there so that we can tell between a detached HEAD and a
confusingly named branch whose name is 40-hex.

Otherwise, one who tries to update that "has changed from '%s'"
message to clarify between "pointed at branch '%s'" and "pointed at
commit '%s'" (or translate into a language where the distinction
matters, perhaps because branch and commit have different gender
there that affects conjugation for "has changed from" part, or
something hand-wavy) have insufficient information to work with.

Thanks.
