paranoid-pray vs do-again

If paranoid_confirm settings include praying, don't put the answer
to "are you sure you want to pray?" into the do-again buffer where ^A
would use it to ignore confirmation if prayer is repeated.  And for
wizard mode, when confirmation is 'y' then the answer to "force the
gods to be pleased?" has to be suppressed from the do-again buffer too
or it would be used by subsequent ^A to answer "are you sure?".

This is basically a band-aid just for #pray.  There are probably other
confirmations that should be suppressed from do-again instead of being
reusable.  The rest of the paranoid_confirm ones should be ok because
they require "yes" and that doesn't end up in the do-again buffer, but
there are bound to be other confirmations that shouldn't automatically
be re-used during repetition.
