Subject: [PATCH 1/3] erl_docgen: Fix highlight js bug on pages with id=export

Due to a quirk in JS (where it creates global variables
containing the object that the id points to) the hljs
crashed when starting which caused some pages to be
rendered without syntax highlighting. For example
erl_error.
