+Markup languages support

+correctly on the slave pages:

+* [[reStructuredText|rst]]: anonymous hyperlinks and internal
+  cross-references
+* [[wikitext]]: conversion of newlines to paragraphs
+* [[creole]]: verbatim text is wrapped, tables are broken
+* [[html]] and LaTeX: not supported yet; the dedicated po4a modules
+  could be used to support them, but they would need a security audit

-Page titles in links
---------------------
-
-To use the page titles set with the [meta](plugins/meta) plugin when
-rendering links would be very much nicer, than the current
-"filename.LL" format. This is actually a duplicate for
-[[bugs/pagetitle_function_does_not_respect_meta_titles]].

-Page formats
+Better links

 ------------
 
 ------------
 

-Markdown is well supported, great, but what about others?
-
-The [po](plugins/po) uses `Locale::Po4a::Text` for every page format;
-this can be expected to work out of the box with most other wiki-like
-formats supported by ikiwiki. Some of their ad-hoc syntax might be
-parsed in a strange way, but the worst problems I can imagine would be
-wrapping issues; e.g. there is code in po4a dedicated to prevent
-re-wrapping the underlined Markdown headers.
+### Page title in links

 
 

-While it would be easy to better support formats such as [[html]] or
-LaTeX, by using for each one the dedicated po4a module, this can be
-problematic from a security point of view.
-
-**TODO**: test the more popular formats and write proper documentation
-about it.
+Using the fix to
+[[bugs/pagetitle_function_does_not_respect_meta_titles]] from
+[[intrigeri]]'s `meta` branch, the generated links' text is based on
+the page titles set with the [[meta|plugins/meta]] plugin. This has to
+be merged upstream, though.
