I think the Git test cases prefer "test" over "[]":

	if test -n "$1"
	then
		local dir="$1/"
	else
		local dir="$1"
	fi

And should there be a && after the "fi" ?
And as test -n tests for a non-zero string,
could we write like this (and drop the local ?)?

	if test -n "$1"
	then
		dir="$1/"
	else
		dir=""
	fi
