A 971

While common sense might dictate that the effects of the spell applies separately on each hit made with that full attack, the wording only specifies that the spell affects each target you hit in that round; such wording usually means each target is only affected once by that spell. It's ambiguous enough to defy a completely solid RAW answer.

A 972

By RAW, it appears that a wish can only be "perverted" if it asking for an effect greater than that listed.

You may try to use a wish to produce greater effects than these, but doing so is dangerous. (The wish may pervert your intent into a literal but undesirable fulfillment or only a partial fulfillment.)

If you're choosing an effect from the provided list, you should therefore get what you asked for without trouble.

Side note: this assumes you are the caster... if you are gaining a wish from a reluctant provider, the actual caster has every right to twist your words as much as they can get away with, if he/she/it wants to.
