doc: Improve explanations when a table rewrite is needed

Further improvement for commit 11bd8318602.  That commit confused
identity and generated columns; fix that.  Also, virtual generated
columns have since been added; add more details about that.  Also some
small rewordings and reformattings to further improve clarity.
