"the user name can't change while the document is protected" was the
wrong term twice over: it is the session author — the name new tracked
changes and comments are recorded under, and the one a named exception
is matched against — and it is `file.setAuthor` that refuses to change
it. The CLI's `--author` names the session directly, so it works on a
protected document.
The parity row, the two status lines and the two progress rows now say
that.
