  11 <p>When ReplaceSelectionCommand deletes the current selection, it should request that the deletion do a merge in some cases (normally, though, it should ask that a merge not be done, because a merge will cause information about block nesting to be lost).  It wasn't requesting a merge in cases where it should have.</p>
  12 <p>The failing case is where the incoming fragment has more than one block, and the selection being pasted into ends at the end of a paragraph.  Any time the selection being pasted into ends at the end of a paragraph, deleting will leave leave a) a br or b) an empty block at the end of the deleted selection.  So, not merging will leave an extraneous empty line or a collapsed block after the paste operation.</p>
