whitespace trimming within pre tags

[David Au]

Leading whitespace within a pre tag is being trimmed. This is an issue because the text within the pre tag is expected to be preserved 'as is'.

1. To reproduce this issue, paste the following into FCKeditor's Source view:

   <pre>
     /***
      * First line (above) has leading whitespace.
      * Some more text...
      */
      public void testFunction(){
        System.out.println( "abc" );
      }
   </pre>
   

2. Next press the Source button to return to the normal view.
   
3. Now press the Source button two more times and you will see that the leading whitespace on the first line has been removed.

This issue exists on Firefox 2.0.0.3 and IE 7.0.5730.11 (both on WinXP).
