Subject: [PATCH v2 1/5] mailinfo: avoid magic number in option parsing
Date: Wed,  5 May 2021 00:19:58 +0700	[thread overview]
Message-ID: <e1e0d8196197d0eb3a39454a48b112a5843d33d7.1620148732.git.congdanhqx@gmail.com> (raw)
In-Reply-To: <cover.1620148732.git.congdanhqx@gmail.com>

While current magic number is perfectly correct, in a later change,
we would like to parse for another option, namely "--quoted-cr".
Let's refactor a bit to remove that magic number.
