[log5-devel] Negation does not work in sender spec

[Ilya Perminov]

Hi,

The following code gives "Variable BAR undefined" error:
(defcategory foo)
(defcategory bar)
(start-sender 'console-log1
                 (stream-sender :location *error-output*)
                 :category-spec (and foo (not bar))
                 :output-spec (category message))

I think the problem is in sender-responds-to-category-p. 
determine-category-variables returns two list, but 
sender-responds-to-category-p does not use the second one
(negated variables).

Regards,
Ilya
