* Fix the htmltidy plugin, which wasn't working due my breaking it when

[ikiwiki] / doc / plugins / htmltidy.mdwn

This plugin uses [tidy](http://tidy.sourceforge.net/) to tidy up the html

even if users enter suboptimal html, your wiki generates 100% valid html.

This plugin is included in ikiwiki, but is not enabled by default.
