 Let's say that the glob instead returns a HardFailReason, which when

+Question: Are all pagespec terms that return reason objects w/o any
+influence info, suitable to block influence in this way? 
+
+To be suitable to block, a term should never change from failing to match a
+page to successfully matching it, unless that page is directly changed in a
+way that influences are not needed for ikiwiki to notice. But, if a term
+did not meet these criteria, it would have an influence. QED.
