Since 8cbeba0632 (tests: define GIT_TEST_PROTOCOL_VERSION,
2019-02-25), it has been possible to run tests with a newer protocol
version by setting the GIT_TEST_PROTOCOL_VERSION envvar to a version
number. Tests that assume protocol v0 handle this by explicitly
setting
GIT_TEST_PROTOCOL_VERSION=
or similar constructs like 'test -z "$GIT_TEST_PROTOCOL_VERSION" ||
return 0' to declare that they only handle the default (v0) protocol.
The emphasis there is a bit off: it would be clearer to specify
GIT_TEST_PROTOCOL_VERSION=0 to inform the reader that these tests are
specifically testing and relying on details of protocol v0. Do so.
This way, a reader does not need to know what the default protocol
version is, and the tests can continue to work when the default
protocol version used by Git advances past v0.
