Yes, we explicitly clear "-c" variables when we cross repo boundaries.
You can do it like:

  git push --receive-pack='git -c transfer.hideRefs=...  receive-pack'

but that is probably more obfuscated than using test_config.

I was going to complain that "test_config -C" does not actually work,
but somehow I missed 5fafc07 (test-lib-functions: support "test_config
-C <dir> ...", 2015-09-05) going by. Very cool.
