[RFA] Fix/improve on-line help of 'define' command.

  While I was playing with 'define' to understand how some quoting was
done (or not done), I found an inconsistency between the doc
and the online help.
=> the doc is correct, so fixing/improving the on-line help.

	* cli/cli-script.c (_initialize_cli_script): Fix online documentation
        of 'define' command.
