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?
+ (Although that would mean that [[bugs/broken_parentlinks]] would not be
+ fixed en passant by this patch..)

* 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.

+
+ if ( !length $to ) {
+ return baseurl($from);
+ }
+
+
+* It calles abs2rel about 16% more often with the patch, which makes it
+ a bit slower, since abs2rel is not very efficient. (This omits abs2rel
+ calls that might be memoized away already.) This seems to be due to one
+ extra abs2rel for the toplevel wiki page due to the nicely cleaned up code
+ in `parentlinks` -- so I'm not really complaining.. Especially since the
+ patch adds a new nice memoizable `urlto`.
+* The rss page name generation code seems unnecesarily roundabout, I'm sure
+ that can be cleaned up somehow, perhaps by making `htmlpage` more
+ generic.
+
+ > Something like `targetpage(basename, extension)`?
+

+
+* `aggregate.pm` uses htmlpage in a way that breaks with its new behavior.
+ It will need to be changed as follows:
