Link: http://rakesh.fedorapeople.org/misc/0001-pfunct-Introduce-u-all_units.patch

Reason I am not reusing cus__for_each_cu which in turn uses
cu_function_iterator is because it would have in my view been more
unclean way of doing it. To keep things simple and clean I am rather
using a static function print_all_matches.

May this be reviewed ?

Regards,

Continue printing all function name matches.
