There is another consideration here, which is avoiding creating
back-patching hazards from gratuitous cross-branch code differences.
If you need to rewrite a chunk of logic anyway, then fixing
small cosmetic issues in it is fine. Otherwise I think "leave
well enough alone" is a good guiding principle.
