Subject: [PATCH v5 18/34] merge-recursive: make !o->detect_rename codepath more obvious
Date: Wed, 27 Dec 2017 20:13:36 -0800 [thread overview]
Message-ID: <20171228041352.27880-19-newren@gmail.com> (raw)
In-Reply-To: <20171228041352.27880-1-newren@gmail.com>
Previously, if !o->detect_rename then get_renames() would return an
empty string_list, and then process_renames() would have nothing to
iterate over. It seems more straightforward to simply avoid calling
either function in that case.
