+Implementing tags in terms of links is clever, but it would be nice if it was
+opaque in both directions: tagging and matching tags. Writing pagespecs to
+find out which pages are tagged with a given name means that the pagespec is
+tied to whatever the tagbase is.
+
+This patch adds a pagespec function 'tag' which lets you write pagespecs to
+match tagged pages independent of whatever the tagbase is set to.
