Minor nit on changes to past versions

[Bill Studenmund <wrstuden@wasabisystems.com>]

I was going through the Change Log, and noticed something. The changes
between drafts 9 and 10 mentions 'allow 0 in LogoutLoginMax and Min' but I
couldn't find LogoutLogin{Min,Max} mentioned anywhere.

I assume these are references to LogoutLogin{Min,Max}Time keys, which were
later renamed to DefaultTime2Wait & DefaultTime2Retain?

Take care,

Bill
