I have made the change alluded to here, in the commit
168165178f32fb4e20aea32858407921baf079f0, which has been pushed to the
emacs-29 branch.  This has also allowed for some other simplifications
to be made, which is nice.

The above `package-vc-install' now works on my end, and I see the Loopy
manual listed under (dir)Top.
