What are overlays? The problem occurs because LaTeX-Fill-Paragraph 
formats text according to the underlying source code, it doesn't know 
about the inline images. An formatting algorithm that might work would 
be something like this:

1. Go to the beginning of a paragraph. 
2. Remove all newlines from that paragraph
3. Set the variable LINE_WIDTH to 0.
4. Add the width of the next visible entity (single character, inline
   image, ...) to LINE_WIDTH.
5. If LINE_WIDTH > MAX_LINE_WIDTH then
     a) In the paragraph add a newline before the last entity processed.
     b) Go back one entity.
     c) Continue at step 3 unless we're finished with formatting the
        paragraph.
   else
     Continue at step 4.
