Dunno, sh_* seems clear enough for me.  Anyone who writes shell applets
(I hate that word) for these sorts of purposes is going to have to
learn to be careful about a lot more than the input arguments, if they
care about security.  Perhaps 'requote' is only clearer to former
Multicians -- of which I know exactly one.

I'll leave it up to whoever wants to integrate the patch.
