Jerzy, All,

Is that a fix for the existing issues, or just an improvement/cleanup?

Why do we need an initial value in the arrays? Can't we do something
like:

    package = []
    ...
    if level > len(self.package):
        append the stuff here.

Of course, that is not very nice either... All of that because we can't
assigne to an index that does not already exists. In python, the moto is
"easier to ask for forgiveness than permission". So:

    try:
        self.menu_of_packages[level] = text[:-1]
        self.package[level] = ""
        self.print_package_warning[level] = True
    except IndexError:
        self.menu_of_packages.append(text[:-1])
        self.package.append("")
        self.print_package_warning.append(True)

Regards,
Yann E. MORIN.

That is just improvement.

We don't need it.

I'm fine with your suggestion too.
I'll send a new version in a couple of days.
Thanks for the review.
