I don't know the reason of the rgrep authors (though I suspect it was
portability concerns), but I have noticed something odd about "grep -r":
-- sometimes it seems _much_ slower than "find ... -type f | xargs grep"
on very large trees (I think I noticed with trees in NFS, where speed is
a perennial issue).  Dunno why this...
