-A C expression which determines whether the option @option{-@var{name}}
-takes arguments. The value should be the number of arguments that
-option takes--zero, for many options.
-This macro does not need to handle options defined in @file{.opt}
-files, only those that are handled purely through specs.

-should call @code{DEFAULT_WORD_SWITCH_TAKES_ARG} and then check for
