Subject: [PATCH 8/8] common/parser.c: Do not treat zero return code as error
Date: Sun, 11 Oct 2015 11:43:41 -0700	[thread overview]
Message-ID: <1444589021-12727-8-git-send-email-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <1444589021-12727-1-git-send-email-andrew.smirnov@gmail.com>

Run_command() would return zero to indicated success so treating it as
error case would completely break command repetition logic, so change
comparinson operator from "less or equal" to "less then"
