Thank you for pointing out this docbug. This is based on an early
version of the patch series and should have been changed.

Please see this patch which attempts to do a better job. I can
create a new thread with this submission if we need more edits.

Thanks,

Subject: [PATCH] maintenance: properly document --schedule
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The documentation for the '--schedule' option is incorrect and based on
an early version of the background maintenance feature. Update the
documentation to describe the actual use of the option.

The most important thing is that Git takes this option as a hint for
which tasks it should run. Users should not run this command arbitrarily
and expect that Git will enforce some timing restrictions.
