* command-line-parser.dylan
  (parse-command-line): Pass usage and description to %parse-command-line
    and let that function handle printing the synopsis when requested.
    Also, only print the <usage-error> if it isn't a <help-requested>.
  (%parse-command-line): Print the synopsis when requested.

* tests/command-line-parser-test-suite.dylan
  (test-min-max-positional-options): Add test to be sure that help is
    handled, despite invalid positional args.
