After proving out git stash for a very long time as a shell script, we
eventually converted it to a proper built-in, leaving an escape hatch in
place to call the scripted version.

After another very long time, we removed that escape hatch, leaving behind a
warning.

Now, almost two years later, let's remove even that warning (and a couple of
tidbits that we inadvertently left in the code base).

Johannes Schindelin (4):
  git-sh-setup: remove remnant bits referring to `git-legacy-stash`
  add: remove support for `git-legacy-stash`
  Remove documentation for `stash.useBuiltin`
  stash: stop warning about the obsolete `stash.useBuiltin` config
    setting
