def sanitize_value(nodes)
  nodes.pop if (nodes.last.is_a?(Pre) || nodes.last.is_a?(Text)) && nodes.last.text =~ /^\s*$/ # FIXME: dirty!
  nodes
end

#template ⇒ Object

NB: here we are not distingish templates like {{Infobox|variable}} and "magic words" like {{formatnum:123}} Just calling all of them "templates". This behaviour will change in future, I presume More about magic words: https://www.mediawiki.org/wiki/Help:Magic_words
