Wasn't the problem how to find the right, in this case,
"target.txt" in a situation like this:

/home/incal/test/dired:
  lrwxrwxrwx 1 incal 10 May 23 22:41 target-link.txt -> target.txt
  -rw-r--r-- 1 incal  0 May 23 22:41 target.txt

Search for "target.txt". When you find it, use

  (get-text-property (point) 'dired-filename)

Here it is nil:

  lrwxrwxrwx 1 incal 10 May 23 22:41 target-link.txt -> target.txt
                                                        ^
So search again, here it is t:

  -rw-r--r-- 1 incal  0 May 23 22:41 target.txt
                                     ^

and that's the target you are looking for.
