I came up with this test earlier today when responding in this thread:
diff --git a/t/t7201-co.sh b/t/t7201-co.sh
index be9672e..a32ecd9 100755

but it feels a little fake. Why 200? Because that will test the config
limit, but will not overflow the NAME_MAX limit (at least not on
Linux! No clue on other platforms) when we try to create
refs/heads/foo-$z200.
So while this is a nice concrete user-visible impact of Ben's patch, I
think it is a little flaky to be testing. We should probably have a
straight config test in t1303, though.
