This needs to be implemented in the display code.  Currently, mode
line and header line are not scrolled horizontally with the text
(header line is the basis for implementation of tabulated-lists).
Conceptually, scrolling in Emacs moves the viewport, not the text, and
header line is considered to be part of the viewport.

If we do implement that, it should probably be a special minor mode,
since not every header line should scroll with the text.  Patches
welcome.
