From abba35395f859600cca1c04f1eab633963a8646e Mon Sep 17 00:00:00 2001 From: Eric Sunshine Date: Wed, 31 Jul 2013 04:15:43 -0400 Subject: blame: reject empty ranges -LX,+0 and -LX,-0 Empty ranges -LX,+0 and -LX,-0 are nonsensical in the context of blame yet they are accepted (in fact, both are interpreted as -LX,+2). Report them as invalid.
