mknmz handles updated documents and deleted documents in the same way.
mknmz adds the fact which "the information about the updated/deleted document
in the index is no longer usable" to the index.
In the case deletion, that's all. In the case addition, after adding
"deleted information", mknmz add the updated document information as new
