accentuate or indent wrapped lines

["Sebastian Fey" <fey@parsytec.de>]

	hi,
	
	in docbook-xsl it is standard that programlistings are NOT wrapped, but this results in an overflow of the text over the page.
	
	i set the attribute  wrap-option="wrap".
	well the programlistings are wrapped now, but i need to marks these linebreaks, either by an indent or a spezial character.

	

	it is not possible to add sth to the xml, such as line numbers.
	
	thx in advance,
	
	Sebastian
