During my nigthly session I fixed a few glitches in the example theme.
Read them carefully because the other theme might need updating too (I
don't think so though).  I could only commit it now because I didn't
had the time to write up these comments/remarks yet.  So here goes:

1. the comment() function only takes 2 arguments - $thread is no longer
   needed and shouldn't be used in the code either.

2. I added 2 COLSPAN's to fix a <TD> problem in the story() function.

3. <A HREF="">home</A> is will not work properly when using drupal in
   a subdirectory!  Simply use <A HREF="index.php">home</A> instead -
   it does matters. ;-)

4. Removed the $timestamp = format_timestamp(...)'s and used them
   "directly" just like this is done for format_username and others.
   It's generally more consistent now. :-)
