If you're only dealing with a partial screenful of data, you could cut
and paste it into a "here" document:
$ grep foo <<EOF

If you have too much data to paste into a here document, I'm afraid
that you're out of luck. I doubt that bash saves the output anywhere
due to the performance hit and the need to deal with both stdout and
stderr seperately. It sure would be a handy thing to have on the few
occasions when you need it though.
