If I try to use colors in a positional variable metavar value, I get a broken output. Most likely this is because this library was originally written for Python 2.x which did not support positional arguments.
To reproduce the issue:
#!/usr/bin/python3
from argparse import ArgumentParser
from argparse_color_formatter import ColorHelpFormatter
from colorama import *
parser = ArgumentParser(formatter_class=ColorHelpFormatter)
parser.add_argument('withcolors', metavar=Fore.CYAN+"withcolors"+Style.RESET_ALL,
help="this is an example long help text string to show the issue")
parser.add_argument('nocolors',
help="this is an example long help text string to show the issue")
parser.print_help()
