[docs] [issue15258] argparse documentation: Improve optparse section regarding allow_interspersed_args

[Glenn Linderman]

Glenn Linderman <v+python at g.nevcal.com> added the comment:

See also issue 14191, which describes the problems of trying to make argparse achieve the goal of the default optparse handling of allow_interspersed_args !

The documentation for that branch of the feature is also seriously incomplete, and the workaround is more than a single line.
