In https://bugs.python.org/issue11354
'argparse: nargs could accept range of options count'
I explored the option allowing regex style range arguments, such as
nargs='{2,4}' or an equivalent tuple nargs=(2,4).
But that builds on https://bugs.python.org/issue9849, which seeks better error
checking of the `nargs` parameter. In the current implementation, there is no
checking or parsing of the value. The full range of allowable values is
determined by its use in 2 methods:
_get_nargs_pattern
_format_args
