t3701 is not the only test script comparing diffs, many other
tests do so:
$ git grep 'diff --git' t/ |wc -l
835
It's totally inaccurate, but a good ballpark figure.
I think this function should be a widely available test helper
function in 'test-lib-functions.sh', perhaps renamed to
'test_cmp_diff', so those other tests could use it as well.
