* Inspects all lines of the given document and wraps all of them that exceed {@link

*
* <p>
*
* <pre>
* <ol>
* <li>
* Check if the line exceeds {@link CodeStyleSettings#RIGHT_MARGIN right margin}. Go to the next line in the case of
* negative answer;
* </li>
* <li>Determine line wrap position; </li>
* <li>
* Perform 'smart wrap', i.e. not only wrap the line but insert additional characters over than line feed if necessary.
* For example consider that we wrap a single-line comment - we need to insert comment symbols on a start of the wrapped
* part as well. Generally, we get the same behavior as during pressing 'Enter' at wrap position during editing document;
* </li>
