Hello,

** Steps to reproduce:
0) Start Emacs (emacs -Q)
1) Visit the attached file.
2) Turn on truncate lines mode (M-x toggle-truncate-lines)
3) Adjust the width of the emacs frame so that only fields 0 to 8 are visible.
4) Place the point just before `field_10' at line 1.
5) Start keyboard macro recording (<F3>)
6) Type: C-a C-n C-s `|' and repeat C-s until the point reaches
`field_10' again.
7) Type <RET> to end Isearch and <F4> to end macro recording.
8) Now type <F4> to execute the macro.

** Expected result: The point moves to `field_10' at line 3.
** Actual result: The point moves to `field_15' at line 3.
