Yes, the display and the horizontal scrolling is now exactly as I hoped
it would be; many thanks!
There is one minor issue: with auto-hscroll-mode set to `current-line'
and (scroll-left 32 t), when I scroll vertically by holding down <down>
or C-n or <up> or C-p, the motion is less smooth than usual. With the
same auto-hscroll-mode setting but no scroll-left, vertical scrolling is
smoother, but still not as smooth as with auto-hscroll-mode set to t or
nil (with either of these settings, vertical scrolling seems slightly
less smooth with (scroll-left 32 t) than with no scroll-left, though the
difference is less noticeable than with auto-hscroll-mode set to
current-line). But I don't think this is a serious annoyance, so unless
you see an easy fix for it, I think you should commit the patch as is to
master.
