Subject: [RFC PATCH 1/2] notes.c: introduce "--no-blankline" option
Date: Thu, 13 Oct 2022 13:56:53 +0800	[thread overview]
Message-ID: <20221013055654.39628-2-tenglong.tl@alibaba-inc.com> (raw)
In-Reply-To: <20221013055654.39628-1-tenglong.tl@alibaba-inc.com>

From: Teng Long <dyroneteng@gmail.com>

When appending to a given object which has note and if the appended
note is not empty too, we will insert a blank line at first. The
blank line serves as a split line, but sometimes we just want to
omit it then append on the heels of the target note.
