Yehuda Katz 24bad78607 Clean up expansion of external words
Previously, external words accidentally used
ExpansionRule::new().allow_external_command(), when it should have been
ExpansionRule::new().allow_external_word().

External words are the broadest category in the parser, and are the
appropriate category for external arguments. This was just a mistake.
