Well, it will break if $OPTARG contains shell metacharacters; should it
maybe have " " in some places?

Also, is there some reason not to use OPTARG="${OPTARG%/}" instead?  Is
this one of the scripts that tries to stick to least-common-denominator
capabilities and thus can't use the ${...%...} syntax?
