Which do you prefer?

This:

lrwxrwxrwx 1 root root 17 Sep 23 06:07 libpng.so.2 -> libpng.so.3.1.2.6*
lrwxrwxrwx 1 root root 17 Sep 23 05:56 libpng.so.3 -> libpng.so.3.1.2.6*
-rwxr-xr-x 1 root root 151084 Aug 17 19:36 libpng.so.3.1.2.6*

Or this:

lrwxrwxrwx 1 root root 17 Sep 23 06:07 libpng.so.2 -> libpng.so.3
lrwxrwxrwx 1 root root 17 Sep 23 05:56 libpng.so.3 -> libpng.so.3.1.2.6*
-rwxr-xr-x 1 root root 151084 Aug 17 19:36 libpng.so.3.1.2.6*


Is either more correct or bound to cause problems? Or is either just as useful?
