From df33982fce6312203ed7446926f31ed92a8ae1ca Mon Sep 17 00:00:00 2001 From: Jean Chalard Date: Mon, 7 Oct 2013 15:48:04 +0900 Subject: [PATCH] Remove suggestions when string contains a period This is not the right way to do it, but it's simple and will kill the regression. We should investigate why the return values are wrong in this case.
