long code line breaks width (html pre tag) about grails-doc

@graemerocher @jeffbrown @guramritpal-jft, I worked on this issue and found the root cause. As per the title of issue this error is due to the pre tag, I suspected that in a pre tag we have a child p tag with a class - paragraph, we have to add another class which has css property:-

width: {:HINT};
word-wrap: break-word;//or can be skipped if we want a scroll bar

HINT: can be added dynamically according to width of users screen in px or by using media tag i don't know the actual way of doing this.
