+I think this is a bug, particularly if you are using Pandoc's
+[header attributes](http://pandoc.org/MANUAL.html#extension-header_attributes)
+or similar.

+I think we should try to use an existing ID before generating our own, with the

+Text::MultiMarkdown or Pandoc is generating worse IDs than this plugin, the
