A set of different behaviour depending on .type is OK, but then at
least the above should be more like this:

	if (options.type == REBASE_APPLY) {
		if (ignore_whitespace)
			argv_array_push(...);
	} else {
		/* REBASE_MERGE and PRESERVE_MERGES */
		if (ignore_whitespace)
			string_list_append(...);
	}

or even

	switch (options.type) {
	case REBASE_APPLY:
		...
		break;
	case REBASE_MERGE:
	case REBASE_PRESERVE_MERGES:
		...
		break;
	default:
		BUG("unhandled rebase type %d", options.type);
	}

That would clarify the flow of the logic better.

Thanks.
