Depending on the project, people may want to customize other aspects of
the summary generation, e.g. rejecting the overhead of -f-c-h.

Why not do it like this intead?

	diffopts=$(git config hooks.diffopts)
	: ${diffopts:="--stat --summary --find-copies-harder"}
        
	echo "Summary of changes:"
        git diff-tree $diffopts $oldrev..$newrev
