Sorry.  I meant that you should not have to review the doc/ part of the
patch, which is unchanged since the last time I submitted it.  I did not
add any text specific to watchpoints, etc., on the grounds that the
entire chapter already appears intended to describe expressions in
general, and apparently has been understood as such up until now.
