It is consistent with the description in the proposed log message ...

... to disable commit graph when "--verify-objects" is requested.

OK.  I missed this when-finished thing in my first read and wondered
who takes care of the 'backup' file.  We obviously cannot use it in
tests that do not follow the "break single loose object and inspect
the command behaviour in the repository" pattern, but that is OK.
