I vote against using a prefix arg for anything like this.  There are
better things to use a prefix arg for.

Instead, either choose a different key altogether for backward q-r or
do not bind a key for it at all.

Just one opinion.


FWIW, I bind `M-%' to a command that rolls together these q-r
behaviors:

* No prefix arg: string q-r (like vanilla `query-replace')
* Negative prefix arg: regexp q-r
* Non-negative prefix arg: word q-r (like vanilla `query-replace')
