I have typed that text, not changed the original so this is not a fix
to your text. Anyway for me "should not" is more polite, like "you
should not yell" meaning you really can not do it. Or "you should not
disrespect the captain".
But that is not a fix.

So I need to explain the solution:
When config core.logAllRefUpdates is set to false what really happens
is that the reflog is not created and any reflog change is saved only
when you have an existent reflog.
What I did was to make a "touch reflog". Creating it, when the new
branch get eventually saved then the reflog would be written normally.
But in case somebody give up this new branch before the first save,
moving back to a regular branch would leave a ghost reflog.
I have coded the cleaning commands for that and the test is just a
check of this behavior.
The first "test -f .git/logs/refs/heads/eta" tests if reflog was
created and the second if it was deleted. No big deal.
Regards
