OK, no, what I mean is this:

   <div style="display: float; width: 10em; height: 6em; border: 2px solid black;
   margin: 0.5em">Float</div>

   <blockquote>This is a quotation</blockquote>

   <p>Lorem ipsum dolor</p>

This will produce:

+------------------+ This is a quotation
|Float             |
|                  | Lorem ipsum dolor
|                  |
|                  |

The blockquote normally has a left margin relative to its parent container, but 
when it sits to the right of a float, it doesn't. I would guess that there's a 
nasty hack somewhere for this, too, but IMO a left margin on an element to the 
right of a float, should be obeyed.

Both padding-left and margin-left are relative to the container element (here, 
assumably body) and are not influenced by floats. Thus, if you place floats 
within text, any items such as blockquote and bulleted lists will (with 
conventional default styling) get their left margins "removed".
