logwrite is evaluated in the order that the acl is interpreted, so you
should put it at the end of a verbal clause if it depends on expansion
variables set during the clause. message is remembered when it is set and
expanded when the acl finishes, so it should usually be put at the start
of the clause. This trickiness is less than ideal.
