Subject: [PATCH v10 12/36] merge-recursive: move the get_renames() function
Date: Thu, 19 Apr 2018 10:57:59 -0700 [thread overview]
Message-ID: <20180419175823.7946-13-newren@gmail.com> (raw)
In-Reply-To: <20180419175823.7946-1-newren@gmail.com>
Move this function so it can re-use some others (without either
moving all of them or adding an annoying split between function
declarations and definitions). Cheat slightly by adding a blank line
for readability, and in order to silence checkpatch.pl.
