You can use mlist_grouped(), but it currently only works with glob
patterns, not regexps. Alternatively, you can use list_grouped,
list_pairs or list_strings and manually filter the result. E.g.:

	import grass.script as grass

	maps = [map
	        for map in grass.list_strings('rast')
	        if map.startswith('rast_') or map.startswith('crast_')]
	maps = ','.join(maps)

	grass.run_command("r.series", input = maps, ...)
