Sorry, this script has to be called with --internal.

This script exists solely for backwards compatibility with the previous
iteration of list-identifiers.sh, of which only the --internal option remains in
use. It is a thin wrapper around list_internal_identifiers.py.

check-names.sh, which used to depend on this script, has been replaced with
check_names.py and is now self-complete.
