Avoid uninitialized value error in help output.

Technically simply passing an unitialized (indeterminate) arg value
to the help_print_option function has undefined behaviour even though
it is only unset in cases where it will not actually be used by the
function.  But it is easy to just ensure it has a well-defined value.
