 OK, I took a shot at implementing the changes. I was thinking about making
 pagespecs relative by default but I couldn't decide whether page
 `foo/bar` inlining `*` should match `foo/bar/*` or `foo/*`.

+One last thing -- could you either change:

+
+to 
+
+                $from=~s!/?[^/]*$!!;
+
+Or could you put in:
+
+                $glob =~ s!//!/!g;
+
+somewhere? Or should I just add this to my index patch? --Ethan
