Inconsistent coloring of args in the top usage panel

i can't seem to upload screenshots but i also have a weird miscoloring - in [--max-decode-length MAX] only in the top panel... the length is a brighter shade of pink.

This is a bug caused by the current use of Syntax with awk lexer . It miscolors other awk keywords as well such as print.

# $ cat t.py:

import argparse
from rich_argparse import RichHelpFormatter

parser = argparse.ArgumentParser(formatter_class=RichHelpFormatter)
parser.add_argument("--max-decode-length", metavar="MAX")
parser.add_argument("--text-to-print", metavar="STR")
parser.print_usage()

# $ python -m t
