The "table-of-contents" in the update hook script should match the body

44478d99ee0 introduced a filter using "git-rev-parse --not --all" to the
log display to prevent the display of revisions already in the
repository.  However, the table of contents generation didn't get that
same update.

This patch fixes that.  The table of contents before the log and the log
now both display the same list of revisions.
