Yeah, that is the point. I realized the existence of the header
line makes the cursor get stuck in a long line. A bug report I
sent follows (use <11261@xxxxxxxxxxxxxxx> to reply to this).

Subject: 24.1.50; cursor doesn't move in a long line
Hi,
When I view an html source, of which lines are very long, I meet
with a symptom that C-f, C-b, and so forth don't move the cursor.
One discovered yesterday that it happens only when the header line
exists in a buffer (we use emacs-w3m that ises the header line for
the tab browsing). Here's a recipe to reproduce this with Emacs -Q:
(let ((fox "The quick brown fox jumps over the lazy dog."))
(pop-to-buffer "*testing*")
(erase-buffer)
(setq header-line-format fox)
(dotimes (var 1000)
(insert fox " "))
(goto-char (point-min))
(search-forward "fox" nil t 500))
Could this be fixed?
Thanks in advance.
Regards,
