    fix various derivative functions
    
    2009-08-14  Andreas J. Guelzow <aguelzow pyrshep ca>
    
    	* derivatives.c (help_opt_bs_carrycost): fix description
    	(help_opt_complex_chooser): This should not have a call_put flag
    	(derivatives_functions): fix number of arguments for opt_bs_delta,
    	  opt_bs_rho, opt_bs_theta, and opt_bs_carrycost
