You can force a clone (at least, not sure about fetch) to use the
git protocol by --no-local, and then you can set
uploadpack.{allowTipSHA1InWant, allowReachableSHA1InWant,
allowAnySHA1InWant} as neded by the test.

From the fetch man page:
For local repositories, also supported by Git natively,
the following syntaxes may be used:

       ·   /path/to/repo.git/

       ·   file:///path/to/repo.git/

These two syntaxes are mostly equivalent, except
when cloning, when the former implies --local option.

Thanks,
Stefan
