Subject: Reverse direction of filter list
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c3df8cdad19da5b51bfdade1e897fa6348cbc900;p=dpkg

Reverse direction of filter list

Insert items into the filter list at the tail rather than at the head,
this makes it easier for users to understand what's going on.
