Subject: [RFC PATCH 1/3] diff: avoid redundantly clearing a flag
Date: Fri, 11 Aug 2017 15:49:14 -0700 [thread overview]
Message-ID: <ae81b1cf697b2d541eadd21b40ead497a0c32eb9.1502491372.git.jonathantanmy@google.com> (raw)

In-Reply-To: <cover.1502491372.git.jonathantanmy@google.com>
No code in diff.c sets DIFF_SYMBOL_MOVED_LINE except in
mark_color_as_moved(), so it is redundant to clear it for the current
line. Therefore, clear it only for previous lines.
This makes a refactoring in a subsequent patch easier.
