Subject: Wrong cursor positioning with display+invisible

[Message part 1 (text/plain, inline)]

Package: Emacs
Version: 24.0.94

Extract the test.cpio and cpio-mode.el files attached, and then try:

   src/emacs -Q -l .../cpio-mode.el .../test.cpio

First, you'll note that the cursor is displayed at end-of-line (whereas
in reality point as it BOB), then move forward with C-f and you'll see
the cursor jumping in odd ways (often being pushed to end-of-line even
when we're still in the middle of the line).

In Emacs-23, the cursor jumps correctly over the various display and
invisible fields, so this is a regression.
