Added a <LimitExcept method ...> sectioning directive that allows

the user to assign authentication control to any HTTP method that
is *not* given in the argument list; i.e., the logical negation
of the <Limit> directive.  This is particularly useful for controlling
access on methods unknown to the Apache core, but perhaps known by
some module or CGI script.
