Actually, it is desirable, and arguably it's the only correct
answer. PmWiki is used in a large number of laboratory and classroom
environments, where multiple people end up using the same machine
to access a common wiki on a daily basis. In these situations,
people think of "logout" as meaning "remove my association with
this particular terminal" -- including their author name.
In fact, many people would be very surprised if the "logout" action
*didn't* cause their author name to be removed from the forms;
"logout" should mean "I'm no longer here." Indeed, this is one
of the reasons ?action=logout was originally created...to provide
an easy way to clear the author cookie.

It's even more inconvenient for an author to try to remove his/her
name from a machine if ?action=logout doesn't do it.
Still, if the admin doesn't want ?action=logout to remove the
author cookie, then use:
$LogoutCookies = array_diff($LogoutCookies, array($AuthorCookie));
which means that ?action=logout won't remove the author cookie.
If there's enough people who think that author cookies should
survive ?action=logout, we can create a special $Enable... variable
for it, otherwise I'll simply cite the above code as a potential
