Redmine

This nice feature which is committed in r1955 with minor changes.

One thing concerning your RD plugin:
I removed the jstoolbar stylesheet include tag from the base layout so that plugins can use other libraries to render the toolbar. So, you'll have to add it in #heads_for_wiki_formatter. It would look like this:

def heads_for_wiki_formatter
  stylesheet_link_tag('jstoolbar') +
  stylesheet_link_tag('rd', :plugin => 'redmine_rd_formatter')
end

Your plugin was tested OK with this change.

Concerning your second patch, I prefer to keep the Textile formatter bundled in the app because I don't want to rely on Engines' mirror files mechanism for such a core functionality.

Thanks.
