Fwiw, the page was written to be a `./sync-all`-agnostic on purpose (in
fact, ./sync-all isn't mentioned only once for pre-submodule trees)

Maybe we need different two different presentations. One concise
reference-like wiki page for Git-gnostic devs, and one for
`./sync-all`-accustomed devs (or maybe even a rosetta-stone like
translation between 'sync-all' invocations, and what the respective
Git-only commands look like)

Fwiw, I have started experimenting with a `runghc`-based ./sync-all
replacement[1] (which uses only the packages bundled with GHC), but I don't
have time to work on it for the next couple of weeks.

      state of your Git repo, and telling you what commands you should
      invoke next, but it's in its really earliest stages. If anyone
      wants to pick it up, and work on it, lemme know.
