Should "ls -R" traverse symlinks?

[Karl Kleinpaste]

Given a directory which contains entries like this ("ls -l"):

total 2
drwxr-xr-x  2 karl           24 May 11 08:41 real-directory
lrwxrwxrwx  1 karl           15 May 11 08:41 netnews -> /usr/spool/news

On a Sun3 running SunOS 3.5.1, "ls -R" does not traverse the "netnews"
symlink.

On a Pyramid running OSx 4.[04], "ls -R" *does* traverse the symlink.

Which is right?
