In check_patch_format we feed $1 to a block that attempts to determine the patch format. Since we've already redirected $1 to stdin there is no need to redirect it again when we invoke tr. This prevents the following errors when invoking git am

  $ git am patch.patch
  tr: write error: Broken pipe
  tr: write error
  Patch format detection failed.
