This changes allows to have multiple mathcing rules in one <match> block
in the same order.
After this changes, the following thing will works as two matching rules:

	<match>
		<!-- rule 1 -->
		<test name="family" compare="eq">
			<string>foo</string>
		</test>
		<edit name="foo" mode="append">
			<string>foo</string>
		</edit>
		<!-- rule 2 -->
		<test name="foo" compare="eq">
			<string>foo</string>
		</test>
		<edit name="foo" mode="append">
			<string>bar</string>
		</edit>
	</match>
