Title: From file

This implements the 'fromfilePrefixChars' feature.

Most of the change is in one function in argument_parser.js
test/fromfile.js implements the corresponding tests from test_argparse.py
It writes several short files to a tempdir

I wonder if there is an example where this feature is genuinely useful.
