I do not like this difference about cvs and svn,
cvs would of given you a ? on a file added to the
tree, svn ingores extra files during a svn diff,
to see extra files in your tree run
svn status
nas1:root {1002}# cd /usr/src
nas1:root {1003}# cd bin/ls
nas1:root {1004}# svn diff
nas1:root {1005}# touch foo
nas1:root {1006}# svn diff
nas1:root {1007}# svn status
? foo
