commit 4779ed9757fa71e6743fb7fc1f9eeae8267ae36c

    Fix selfcheck regression due to new maint command
    
    Simon points out that the new maint command, intended to fix a
    regression, also introduces a new regression in "maint selftest".
    
    This patch fixes the error.  I did a full regression test on x86-64
    Fedora 36.
