Subject: [PATCH 5/8] diff.c: add set_sign to emit_line_0
Date: Mon, 13 Aug 2018 18:41:19 -0700 [thread overview]
Message-ID: <20180814014122.30662-6-sbeller@google.com> (raw)
In-Reply-To: <20180814014122.30662-1-sbeller@google.com>
Split the meaning of the `set` parameter that is passed to
emit_line_0()` to separate between the color of the "sign" (i.e.
the diff marker '+', '-' or ' ' that is passed in as the `first`
parameter) and the color of the rest of the line.
This changes the meaning of the `set` parameter to no longer refer
to the color of the diff marker, but instead to refer to the color
of the rest of the line. A value of `NULL` indicates that the rest
of the line wants to be colored the same as the diff marker.
