There's a version of this in Junio's Git repository as
jt/test-protocol-version, blocked by js/protocol-advertise-multi. After
chatting with Josh (the author of js/protocol-advertise-multi) last
week, it seems that that branch might take a while, so I have decided to
rebase my patches on master.

This necessitates patch 2, which contains additional updates to t5601,
so that all tests pass with GIT_TEST_PROTOCOL_VERSION=1.
(js/protocol-advertise-multi eliminates the need to do that, which is
why these changes did not appear in the previous version.) When
js/protocol-advertise-multi is merged, we can and should revert patch 2.

I have incorporated a small suggestion by Peff [1], and he seems overall
OK with the patch set [2].

I have based my work on the existing contents of
jt/test-protocol-version, so most commits include a "Signed-off-by" line by
Junio. Let me know if you prefer it to be removed.
