This update triggered by suggestion from
  Chris F.A. Johnson, author           <http://shell.cfajohnson.com/>

Did a 'perl -i' style edit on a fairly long list of scripts, that had

  shift $(expr $OPTIND - 1)
Chris points out that forking to run expr for integer math has

it, to see it was outdated"- thanks Chris.

The updated lines look like:

  shift $(( $OPTIND -1 ))

The update is in the usual location:
