I can reproduce the problem:

0. emacs -Q
1. Visit a directory in Dired where you have write permission, e.g. /tmp
   and on some file line there, e.g. .X0-lock, type `S bla RET' to set
   the symlink "bla" to that file.  Now the directory has e.g. this
   entry:
   lrwxrwxrwx  1 steve steve     13 Feb 15 00:31 bla -> /tmp/.X0-lock
2. Type `(' to enable dired-hide-details-mode; now the previous entry
   looks like this:
   bla ->
3. Type `C-x C-q' to enter wdired-mode; now the previous entry looks
   like this:
   bla -> /tmp/.X0-lock
4. Type `C-x C-s' to return to dired-mode; the previous entry still
   looks like this
   bla -> /tmp/.X0-lock
   instead of like this:
   bla ->


With the patch below the result after step 4 is "bla ->".  But I haven't
tested it with any other case, so maybe it has unwanted consequences.
