Wiki revision page does not return 404 if revision does not exist
BUG discovered in wiki revision paths
So like this page only has one revision https://redmine.replicant.us/projects/replicant-infrastructure/wiki/FilteringSpamOnTheMailingList/1
but https://redmine.replicant.us/projects/replicant-infrastructure/wiki/FilteringSpamOnTheMailingList/73 still loads
this can be done with all articles revision pages not just this one.
It is not possible with negative numbers though
