Subject: [PATCH v2 7/7] quote: turn 'nodq' parameter into a set of flags
Date: Thu, 10 Sep 2020 10:01:59 -0700	[thread overview]
Message-ID: <20200910170159.1278781-8-gitster@pobox.com> (raw)
In-Reply-To: <20200910170159.1278781-1-gitster@pobox.com>

quote_c_style() and its friend quote_two_c_style() both take an
optional "please omit the double quotes around the quoted body"
parameter.  Turn it into a flag word, assign one bit out of it,
and call it CQUOTE_NODQ bit.

No behaviour change intended.
