In the patch I just posted to http://bugs.python.org/issue16468 I address this long list issue in several ways:

In the Usage line, the metavar gives the user an alternative

In the expanded help line the user can just omit the '%(choices)s' 

In _check_value(), I implemented a numpy like summarize format for choice lists longer than 15   '{1,2,3,...,18,19}'.
