Thats one I've been chasing and is caused by this same patch. We've lost the separation between command_line and saved_command_line and the user visible line gets trunc'd. Andi has a later version which has this part fixed as far as I can tell. I'm posting a dirty patch in response to my report of this to at least get past this bit as our test system relies on the commmand line being maintained to user space.
