+well. I've rewritten the whole thing, to take into account:
+  
+  * file matching ignoring case (MyPage matches mypage.mdwn)
+  * checking all the way down (up) to the root of the wiki (if there is a link `\[[foo]]` on `a/b/page`),
+  try `a/b/page/foo`, then `a/b/foo`, and so on, up to `foo`
+  * the alternate name for a page: when looking for the file for `\[[foo]]`, try both `foo.mdwn` and `foo/index.mdwn`
+
+you can find the file [here](http://git.devnull.li/cgi-bin/gitweb.cgi?p=vim-jerojasro.git;a=blob;f=.vim/ftplugin/ikiwiki_nav.vim;hb=HEAD). To use it, place it in `$HOME/.vim/ftplugin`. After that, hitting `<CR>` (Enter) in normal mode over a wikilink will take you to that page, if it exists.
+
+the plugin has, as of now, two problems:
+ 
+  * doesn't work with wikilinks that take more than one line (though this isn't really that bad)
+  * it assumes that the root of the wiki is the first directory down the filesystem hierarchy that 
+  has a `.ikiwiki` folder on it. If your copy of the wiki doesn't have it, you must create it for 
+  the plugin to work

 > Interesting. I was at one point looking at "potwiki.vim", which implements a local wiki and follows CamelCase links, creating new files where necessary etc., to see if it could be adapted for ikiwiki (See [[tips/vim syntax highlighting/discussion]]). I didn't get anywhere. -- [[Jon]]
