This allows the browser to download Javascript +files in parallel. + +I have pushed a [simple patch](https://gitlab.com/anarcat/ikiwiki/commit/5caf6e1f87530dda74ec23eb1fa7120309607cc8) which fixes this issue by including +Javascript on the *closing* `` tag instead of the *opening* tag. + +It also improves the regex to tolerate spaces before the `` tag, +as some templates have (proper) indentation for the tag.
