Well it says this regarding OPTIND:

: If the application sets OPTIND to the value 1, a new set of parameters
: can be used: either the current positional parameters or new arg
: values. Any other attempt to invoke getopts multiple times in a single
: shell execution environment with parameters (positional parameters
: or arg operands) that are not the same in all invocations, or with an
: OPTIND value modified to be a value other than 1, produces unspecified
: results.

Unsetting OPTIND ought to do the same thing as setting it to "",
which produces unspecified results and I see nothing wrong with
printing an error in this case.

Cheers,
