I think the code suggested by Junio may be cleaner ;)
I may write as:
if (ignore_whitespace) {
if (options.type == REBASE_APPLY)
argv_array_push(...)
else
string_list_append(...)
}
if (other_condition)
do_something_else(...)
I don't know if it's cleaner or not.
I haven't tried applied it into real code.

I vaguely remember I was thinking about same option text in both leg
would make the code easier for reasoning. And we can unify the
recommendation for both backend. We will never strip
--ignore-whitespace from git-apply, but it would be easier to always
answer: "--ignore-space-change should be used to ignore space" when
someone asks about it.
Typing this now makes me wonder if we should teach --ignore-space-change to
git-rebase?
Thanks,
