In the current version, text imported from Word HTML comes in within a DIV container. I'm guessing that you keep that as a way to reliably replace just the content of the BODY field that's there from the Word doc, so you can have header text or something.

This DIV seems to inhibit the creation of teasers, and it can mess with vertical spacing and indenting on some themes. It would be great if we could have the option to strip this out.
