Macro parameter don't support |-|

From Marius:

Here's an example:

XWiki 2.0 input:

before

{{html foo="x|-|y"}}abc{{/html}}

after

XHTML 1.0 result:

<p>before</p>
<!--startmacro:html|-|foo="x|-|y"|-|abc-->abc<!--stopmacro-->
<p>after</p>

XWiki 2.0 after going back:

before

{{html foo="x"}}y"{{/html}}

after
