Done.  I started out by being cute with plugging "only" or "write"
into a single message, but then figured that might be hard on
translators; so I went with two separate messages.
 
Also, I noticed we seemed to be using "transaction read-only mode"
and "transaction read-write mode" elsewhere, so I made this
consistent with the others while I was at it.  Hopefully that was a
good idea.

Done.
