This behavior still exists in GNU Emacs 23.0.50.4 (i686-pc-linux-gnu,
GTK+ Version 2.12.0) of 2007-11-09 on escher.[1] In addition, starting
with the cursor at (point-min), the line number indicator in the mode
line displays L1, and it continues to display L1 as you advance either
by C-n or by C-f until it reaches the `l' of `line7', then it changes to
L7. From there if you type C-b moving point to just after `6', the mode
line displays L6. Now continuing backwards either by C-p or C-b the
mode line usually continues to display L6, even at (point-min). Typing
C-b again here then changes the display to L1.

Footnotes:
[1] But the behavior seems to be unstable: sometimes line2 is skipped
advancing by C-n, sometimes line6 is skipped receding by C-p (then the
mode line displays L5 and doesn't change as you continue to
(point-min)).
