//No more needing to italicize the punctuation to get rid of the bug!
//Paste your work from Google Docs into the Rich Text editor, then click the Fix Italics (Gdocs) button to remove the improper formatting that adds the unwanted space.
//Will not remove spaces if you paste in, click Preview, go back to the edit page, click Rich Text, then click HTML. In this convoluted case just click Preview and go back to the edit page again and the Fix Italics button will work. Or refresh.
