I couldn't get M-r followed by C-r to work as you described. C-r reverts back to searching the previous pattern I searched with C-r, not the pattern I just searched with M-r.

However, I did not know that after doing the first M-r search, I could just repeatedly do "M-r <RET>" to search for previous occurrences. Still a bit awkward compared to just having to do M-p on xemacs, but at least is another step closer.
