#9444: use first of prefix_chars for help opt instead of raising error
An argparse option parser created with a prefix_chars that did not
include a '-' would happily add -h and --help options, and then throw
an error when it tried to format the help because the - was an invalid
prefix character. This patch makes it use the first character of
prefix_chars as the character for the help options if and only if '-'
is not one of the valid prefix_chars.
Fix by Theodore Turocy, unit tests by Catherine Devlin.

Docs still need some updating to make getopt and optparse match the wording promised in the PEP.
There are also probably a number of :class:ArgumentParser etc. links that could be added to the argparse documentation.
