I think we're going to need a more specific set of reproduction steps,
because adding the following to t5540 succeeds (starting on branch
"dev"):

test_expect_success 'non-force push fails if not up to date' '
	git push origin dev &&
	git reset --hard HEAD^ &&
	: >path3 &&
	git add path3 &&
	test_tick &&
	git commit -m dev &&
	test_must_fail git push origin dev &&
	git push origin +dev
'

That means that this is working in at least some cases.  If you're still
seeing this, can you provide a set of commands (e.g., a shell script) to
initialize and create a new repository that triggers this, provided that
"origin" refers to a suitable remote?
