Subject: [PATCH 09/11] blame: reject empty ranges -LX,+0 and -LX,-0
Date: Wed, 31 Jul 2013 04:15:43 -0400 [thread overview]
Message-ID: <1375258545-42240-10-git-send-email-sunshine@sunshineco.com> (raw)
In-Reply-To: <1375258545-42240-1-git-send-email-sunshine@sunshineco.com>
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.
