For a non-merge changeset, just use hg log -p (for "patch"):
  hg log -r REV -p

But hg log does not have all the diffing options like -w, -b, -U.  For
merge changesets, this only shows you the diff to the first parent. To
see the diff against the other parent, or use diff options, you would
need to use "hg parents" and "hg diff".
