svn list no working for some working directories

Hi All,
My understanding is that 'svn list' will show the contents of the
repository for the same path as the current directory in the workspace.

For example, if my workspace has
dir1/
dir2/
file1

but the repository has a new directory recently added, called dir3,
svn ls would report
dir1/
dir2/
dir3/
file1

i.e. it shows me the contents of the repository.

However, if the local workspace was originally checked out with the -N
(non-recursive) command,
running svn ls would only show me the directories I have, it would not
show me dir3!

This appears to be a bug - becuase if not, what advantage is svn ls over
plain ls, in this case?
I have tested this will the latest svn 1.5.2, and it still operates in
this way.

The same thing goes for svn update, if the local working direcotory was
originally checked out with -N, running svn update will only get the
contents of directories that are in the workspace.
It would be great if there was a switch to force recursion, like -R or
something, or even -R n, where n would be a number of levels.

At the very least, I think this is a bug in the terms of svn ls,
changing svn update to work as described is a bonus!
