Subject: [PATCHv3 06/20] diff.c: emit_line_0 takes parameter whether to output line prefix
Date: Thu, 18 May 2017 12:37:32 -0700	[thread overview]
Message-ID: <20170518193746.486-7-sbeller@google.com> (raw)
In-Reply-To: <20170518193746.486-1-sbeller@google.com>

In later patches we'll make extensive use of emit_line_0, as we'd want
to funnel all output through this function such that we can add buffering
there.
