-A few patches to clean up and improve feed management for inline pages.
+I rearranged my patchset once again, to clearly identify the origin and
+motivation of each patch, which is explained in the following.
-* the first patch simply replaces the id attribute in the default template for feedlinks with a class attribute by the same name. This is necessary in pages with multiple inlines to guarantee correctness
-* the second patch tries to define the default description for a feed based not only on the wiki name, but also on the current page name. The actual way this is built might not be the optimal one, so I'm open to suggestions
-* the third patch passes the feed titles to the templates, changing the default templates to use these as title attributes for the links. a rel="alternate" attribute is also included
-* the fourth patch introduces a feedlinks parameter to the inline directive, to allow for the specifications of the locations where the feed links should appear. Currently, two options are allowed (head and body), plus both and none with obvious significance
+In my ikiwiki-based website I have the following situation:
+
+* `$config{usedirs}` is 1
+* there are a number of subdirectories (A/, B/, C/, etc)
+ with pages under each of them (A/page1, A/page2, B/page3, etc)
+* 'index pages' for each subdirectory: A.mdwn, B.mdwn, C.mdwn;
+ these are rather barebone, only contain an inline directive for their
+ respective subpages and become A/index.html, etc
+* there is also the main index.mdwn, which inlines A.mdwn, B.mdwn, C.mdwn,
+ etc (i.e. the top-level index files are also inlined on the homepage)
+
+With the upstream `inline` plugin, the feeds for A, B, C etc are located
+in `A/index.atom`, `B/index.atom`, etc; their title is the wiki name and
+their main link goes to the wiki homepage rather than to their
+respective subdir (e.g. I would expect `A/index.atom` to have a link to
+`http://website/A` but it actually points to `http://website/`).
+
+This is due to them being generated from the main index page, and is
+fixed by the first patch: ‘inline: base feed urls on included page
+name’. As explained in the commit message for the patch itself, this is
+a ‘forgotten part’ from a previous page vs destpage fix which has
+already been included upstream.

+
+The second patch, ‘inline: improve feed title and description
+management’, aligns feed title and description management by introducing
+a `title` option to complement `description`, and by basing the
+description on the page description if the entry is missing. If no
+description is provided by either the directive parameter or the page
+metadata, we use a user-configurable default based on both the page
+title and wiki name rather than hard-coding the wiki name as description.

+>>>> the code is written already … (but then again I'm known for being a
+>>>> guy who loves options).
+
+The third patch, ‘inline: allow assigning an id to postform/feedlink’,
+does just that. I don't currently use it, but it can be particularly
+useful in the postform case for example for scriptable management of
+multiple postforms in the same page.

+
+In one of my wiki setups I had a terminating '/' in `$config{url}`. You
+mention that it should not be present, but I have not seen this
+requirement described anywhere. Rather than restricting the user input,
+I propose a patch that prevents double slashes from appearing in links
+created by `urlto()` by fixing the routine itself.
+
+> If this is fixed I would rather not put the overhead of fixing it in
+> every call to `urlto`. And I'm not sure this is a comprehensive
+> fix to every problem a trailing slash in the url could cause. --[[Joey]]
+
+>> Maybe something that sanitizes the config value would be better instead?
+>> What is the policy about automatic changing user config?
+
+>>> It's impossible to do for perl-format setup files. --[[Joey]]
+
+>>>> Ok. In that case I think that we should document that it must be
+>>>> slash-less. I'll cook up a patch in that sense.
+
+The inline plugin is also updated (in a separate patch) to use `urlto()`
+rather than hand-coding the feed urls. You might want to keep this
+change even if you discard the urlto patch.
+
+> IIRC, I was missing a proof that this always resulted in identical urls,
+> which is necessary to prevent flooding. I need such a proof before I can
+> apply that. --[[Joey]]
+

+
+>> Aside from that, if I read the code correctly, the only other extra
