[PATCH] __git_commit_objects_prefer_recent: local ret

[Daniel Hahler <genml+zsh-workers@thequod.de>]

From: Daniel Hahler <git@thequod.de>

Without this, `ret` will be set to 1 with `git diff --ex<tab>` and
result in duplicate entries:

   % git diff --ex<tab>
    -- option --
   --exit-code    -- report exit code 1 if differences, 0 otherwise
   --exit-code  -- report exit code 1 if differences, 0 otherwise
   --ext-diff     -- allow external diff helper to be executed
   --ext-diff   -- allow external diff helper to be executed
   --no-ext-diff  -- disallow external diff helper to be executed
    -- recent commit object name --

I am not sure if this is the right way to do it.
