to add the link, the regular dependency calculation code notices that
a new page matches. If a page that had the link is modified to remove it,
didn't notice, since the pagespec no longer matched.

So, seems what is needed is a way for influence info to be manipulated by
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
Then, when NOTting a `*Reason`, swap the two sets of influences.
When ANDing/ORing, combine the individual sets. Querying the object for
influences should return only the successful influences.

+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.)
