Many times, people *want* DOS-hosted utilities to
expand wild cards. As you write, argexpand is one
way to go about that.
It's far from the only one. Alex knows this, of
course, but I want to make it explicit for other
readers. If you're writing a DOS-hosted utility,
think about what you want
or other wildcards to mean. While base Python
doesn't directly support their expansion, it's
easy enough to use glob and helpers.
