+I was suprised that, when using the map directive, a pagespec of "*"
+listed all the translated pages as well as regular pages. That can 
+make a big difference to an existing wiki when po is turned on,
+and seems generally not wanted.
+(OTOH, you do want to match translated pages by
+default when locking pages.) --[[Joey]]
