Subject: Re: [PATCH v2 5/8] tests: add a special setup where for protocol.version

Regarding the subject, I think you mean "add a special setup var", not
"add a special setup where".

Optional: I prefer the "overrides" language used in
GIT_TEST_COMMIT_GRAPH to make it clear that any existing setting is
ignored. E.g.:

  GIT_TEST_PROTOCOL_VERSION=<'protocol.version' config value>, when set
  to a non-empty string, overrides the 'protocol.version' value. E.g.
  "0", ...

Other than that, this patch and the other patches (1-4, 6, 8) look good
to me. My patch 7 looks good too, but it's probably better if someone
else looks at it too :-)
