This is correct.  This successful test can be added to
t3501-revert-cherry-pick.sh:

```
test_expect_success 'cp -r repo in the middle of a revert' '
	test_when_finished rm -r new-repo &&
	test_when_finished rm -r copy-repo &&
	test_create_repo new-repo &&
	(
		cd new-repo &&
		echo nul >test.txt &&
		git add test.txt &&
		git commit -m "Initial commit" &&
		echo test >test.txt &&
		git add test.txt &&
		git commit -m "Changes" &&
		git revert HEAD --no-commit
	) &&
	cp -r new-repo copy-repo &&
	(
		cd copy-repo &&
		# Needed in order to avoid
		#     error: Entry test.txt not uptodate. Cannot merge.
		git update-index --refresh &&
		git revert --abort
	)
'
```
