 the boolean operations that are applied. One way would be to have two
 sets of influences be returned, one for successful matches, and one for

+Would it be possible to avoid the complication of maintianing two sets of
+influence info? 
+
+Well, notice that the influence of `pagespec_match($page, "link(done)")`
+is $page. Iff the match succeeds.
+
+Also, the influence of `pagespec_match($page, "!link(done)")` is
+$page. Iff the (overall) match succeeds.
+
+Does that hold for all cases? If so, the code that populates
+`depends_simple` could just test if the pagespec was successful, and
+if not, avoid adding $page influences, while still adding any other, 
+non-$page influences.

+Hmm, commit f2b3d1341447cbf29189ab490daae418fbe5d02d seems
+thuroughly wrong. So, what about influence info for other matches
+like `!author(foo)` etc? Currently, none is returned, but it should
+be a content influence. (Backlink influence data seems ok.)
