Subject: [PATCH v12 07/13] ref-filter: support printing N lines from tag annotation
Date: Wed, 19 Aug 2015 00:07:26 +0530 [thread overview]
Message-ID: <1439923052-7373-8-git-send-email-Karthik.188@gmail.com> (raw)
In-Reply-To: <1439923052-7373-1-git-send-email-Karthik.188@gmail.com>
From: Karthik Nayak <karthik.188@gmail.com>
In 'tag.c' we can print N lines from the annotation of the tag using
the '-n<num>' option. Copy code from 'tag.c' to 'ref-filter' and
modify 'ref-filter' to support printing of N lines from the annotation
of tags.
