ll-merge: let caller decide whether to renormalize
Add a “renormalize” bit to the ll-merge options word so callers can decide on a case-by-case basis whether the merge is likely to have overlapped with a change in smudge/clean rules. This reveals a few commands that have not been taking that situation into account, though it does not fix them. No functional change intended.
