 ** Changes in behavior
 
-  df, with no non-option argument and recent enough kernel/tools, would
-  print a long UUID-including file system name, pushing second and subsequent
-  columns far to the right.  Now, when that long name refers to a symlink,
-  df prints the usually-short referent instead.
+  df avoids long UUID-including file system names in the default listing.
+  With recent enough kernel/tools, these long names would be used, pushing
+  second and subsequent columns far to the right.  Now, when a long name
+  refers to a symlink, and no file systems are specified, df prints the
+  usually-short referent instead.
 
   tail -f now uses polling (not inotify) when any of its file arguments
   resides on a file system of unknown type.  In addition, for each such
   argument, tail -f prints a warning with the FS type magic number and a
   request to report it to the bug-reporting address.
