Although argparse contains translatable strings, translations for those strings do not ship with Python. This means that any program that uses argparse must separately translate argparse, which is a lot of duplicated work.

Moreover, if argparse is translated downstream, it is only translated against a single version of Python. If a user uses a different version of Python, there is no guarantee that the strings (and thus the translations) will be the same.

Shipping translations for argparse together with Python would solve this issue.

As a caveat, the translations cannot be in `/usr/share/locale` or equivalent. Users may have multiple versions of Python installed, so there would be a namespace conflict.
