+
+----
+
+First pass over Tumov's patch -- which doesn't cleanly apply anymore, so
+I'll attach an updated and slightly modified version below.
+
+* `urlto()` is O(N) to the number of pages in the wiki, which leads to
+ O(N^2) behavior, which could be a scalability problem. This happens because
+ of the lookup for `$to` in `%renderedfiles`, which shouldn't be necessary
+ most of the time. Couldn't it just be required that `$to` be a html page
+ name on input?
+* As we discussed in email, this will break handling of `foo/index.mdwn`
+ pages. Needs to be changed to generate `foo/index/index.html` for such
+ pages (though not for the toplevel `index`).
+* This does make the resulting wikis much less browsable directly on the
+ filesystem, since `dir` to `dir/index.html` conversion is only handled by web
+ servers and so you end up browsing to a directory index all the time.
+ Wouldn't it be better to make the links themselves include the index.html?
+* Some of the generated links are missing the trailing / , which is
+ innefficient since it leads to a http redirect when clicking on that
+ link. Seems to be limited to ".." links, and possibly only to
+ parentlinks. (Already fixed it for "." links.)
+
+This is only a first pass, I still need to check to see if there are any
+code paths where it adds expensive operations such as `abs2rel` that were
+not needed before. And I have not audited all the plugins to see if any are
+broken by the changes.
