Just found the solution. Looking at the source of auth.logout() at
http://web2py.com/examples/static/epydoc/web2py.gluon.tools-pysrc.html#Auth.logout,
there is a line here:
current
<http://web2py.com/examples/static/epydoc/web2py.gluon.tools-pysrc.html#>.session
<http://web2py.com/examples/static/epydoc/web2py.gluon.tools-pysrc.html#>.flash
= self.messages.logged_out
which looks like the cause of session.flash being assigned None.
On chapter 9 of the book (http://web2py.com/books/default/chapter/29/9),
there is a bunch of auth.messages that can be customized, such as the one
for logging out:
auth.messages.logged_out = T('You are logged out.')
Now session.flash (actully response.flash after the redirect) will have
whatever message I set.
