When does the URL of a git-reference include a version?

(guix upstream) expects a single git-reference, not a list of git-
references.

Also, depending on the order of fields here doesn't seem great, I' do
something like

((? git-reference? reference)
 (git-reference
    (inherit reference)
    (commit updated-commit)))

instead.
