0024802: "help" command shouldn't apply implicit rules in definition process of what command description it should show

-When in "help <command>" <command> was exactly found in existing draw commands, then helpstring for this <command> is displayed,
  else "help" fails and error message is displayed
 -When "*word" or "word*" or any other combination is given in args, then help command performs typical wildcard search.
