Subject: [PATCH v5 1/3] color.c: fix color_parse_mem() with value_len == 0
Date: Thu, 19 Jan 2017 18:41:21 +0700	[thread overview]
Message-ID: <20170119114123.23784-2-pclouds@gmail.com> (raw)
In-Reply-To: <20170119114123.23784-1-pclouds@gmail.com>

In this code we want to match the word "reset". If len is zero,
strncasecmp() will return zero and we incorrectly assume it's "reset" as
a result.
