multiple uses of the option are collected into an array of strings.
@G_OPTION_ARG_DOUBLE: The option takes a double argument. The argument
can be formatted either for the user's locale or for the "C" locale. Since 2.12
@G_OPTION_ARG_INT64: The option takes a 64-bit integer. Like %G_OPTION_ARG_INT
but for larger numbers. The number can be in decimal base, or in hexadecimal
(when prefixed with <literal>0x</literal>, for example, <literal>0xffffffff</literal>).
