From: Stefan Beller Date: Sun, 14 May 2017 04:01:04 GMT Subject: [PATCH 06/19] diff: add emit_line_fmt Message-ID: <20170514040117.25865-7-sbeller@google.com> In-Reply-To: <20170514040117.25865-1-sbeller@google.com> In the following patches we'll convert all printing functions to use the emit_line_* family of functions. Many of the printing functions to be converted are formatted. So offer a formatted function in the emit_line function family as well.
