[4.1.3]
* ls -R once again outputs a blank line between per-directory groups of files.
This was broken by the cycle-detection change in 4.1.1.
+* dd once again uses `lseek' on character devices like /dev/mem and /dev/kmem.
+ On systems with the linux kernel (at least up to 2.4.16), dd must still
+ resort to emulating `skip=N' behavior using reads on tape devices, because
+ lseek has no effect, yet appears to succeed. This may be a kernel bug.
[4.1.2]
* cp no longer fails when two or more source files are the same;
now it just gives a warning and doesn't copy the file the second time.
