New lines at the end of block-level elements are lost

XWiki 2.0 input:

paragraph\\

XHTML output:

<p>paragraph<br/></p>

XWiki 2.0 output after re-parsing:

paragraph

Note: \ \ has been transformed in \n.

XHTML output after re-rendering:

<p>paragraph</p>

I think that a new line at the end of a block-level element should be transformed in \ \ rather than \n since \n gets lost.
