I like to think of symlinks as "special files" that can contain arbitrary
text (as used for example by Emacs in its file locking protocol),
but in practice this poses problems, so I think the right answer is
option (1).  See for example ange-ftp.
The reason is that there are elisp routines (such as file-truename
I guess) that do the symlink-dereference manually rather than relying
on the OS to do it for use.
