Thanks a lot -- this is indeed more precise.  (window-hscroll)
does not handle rescaled text very well, whereas this solution
does.

However, when the cursor is right under the header-line, the
expression above returns 'header-line, so I could not use it
for my purpose.

Also, the same expression returns 'header-line when the cursor
is on the _second_ line below the 'header-line -- I haven't
looked for why it does so, but if it is reproducible, maybe
there is something inconsistent here.

Thanks again anyway!
