 Let's say I have four top level pages with IDs 1,2 and 3 and each has
 three children, say, (11,12,13), (21,22,23) and (31,32,33).

 If I run
 {{{
 <?php wp_list_pages(); ?>
 }}}
  on that I'll get all the pages shown. So it'll be a list like:

 {{{
 1
     11
     12
     13
 2
     21
     22
     23
 3
     31
     32
     33
 }}}


 If I run
 {{{
 <?php wp_list_pages(exclude=3); ?>
 }}}
  then page 3 will not be shown and the hierarchy will collapse so 31,32,33
 appear in the top level of the hierarchy. So what I'll get is:

 {{{
 1
     11
     12
     13
 2
     21
     22
     23
 31
 32
 33
 }}}

 Given the existence of a separate ''exclude_tree'' argument, that is
 pretty much what I'd expect to happen, after all it has to show the child
 pages somehow. If I now introduce a ''depth'' argument so it is:
 {{{
 <?php wp_list_pages(depth=3&exclude=3); ?>
 }}}
  I'd expect the same thing to happen as the ''depth'' shouldn't make any
 difference. What actually happens is that the
 ''exclude'' now behaves similarly to ''exclude_tree''. What I actually get
 is:

 {{{
 1
   11 12 13
 2
   21 22 23
 }}}

 Now that to me doesn't make sense.
