Subject: [PATCH] Modified slighty the format_text() function!! Now, in PLAIN
 AND WIKI formats, the rebuildnolinktag() function is called to rebuild:

    &lt;nolink&gt;  to <nolink> again (open and close tags)

This should avoid showing the "<nolink>" word always in this formats!!

Used to solve Bug 1232 and potentially, others...
(http://moodle.org/bugs/bug.php?op=show&bugid=1232)

Please check it because it's really a CORE change!!
