Alright, I've bisected it.  After step 3, additionally eval this form:

    (define-key project-prefix-map "L" #'vc-print-root-log)

I have this because I want to be able to type just L instead of C-x v L.
That doesn't work -- possibly not a bug -- but surely adding that
binding shouldn't affect C-x v L, at least?
