### When a subtree is formatted separately, the mergeSubtree() step mostly has
### no effect because the subtree's cost and overflow doesn't affect the
### winning solution. But it sometimes does. None of the existing tests happen
### to hit a case that does, but when formatting a corpus with subtree merging
### on and off, this was a relatively simple example where the behavior differs.
