Withdrawn. My error. I missed the part of the documentation that says a
*tuple*, not the list that I tried, does just what I wanted.

New submission from Andy Harrington :
I now set the help string for an
argparse option with two parameters:
parser.add_argument('-s', '--substitute', nargs=2,
help='Replace first string with second',
metavar='string')
which generates a help message
-s
