Hi Tamas. Just use `choose-grep-buffer', instead of `q'. That will switch to
another grep buffer in place of the current one. The default value is now
the last-used grep buffer, so just use M-n to get that.

Download the latest compile+20.el - I just added the completion default. I
hadn't bothered to do that before (grep+.el uses `grep-last-buffer', which
isn't defined in Emacs 20).
