We tracked one decor per key.
When dealing with dotted keys,
we used the decor prefix from the first key.
The problem is that we then re-encode that key for each dotted key,
duplicating any comments or whitespace associated with it.

We solved this by tracking decor between dotted keys separate from the
decor used per final, or leaf, entry.

Fixes #673
