bug#35659: 26.1; Weird horizontal scroll behavior with certain settings for `auto-hscroll-mode' and `hscroll-step`.

Sorry, it seems I was wrong. The window stays scrolled for the shorter lines 
here, as well (unless it's an empty one, then the scrolling resets).  

Still I think when the shorter lines don't get pushed around
with hscroll-step 0, it shouldn't happen with hscroll-step set to another value.

Thank you for doing it, it's really a great feature and I like it. I guess
I have to live with the default setting for hscroll-step then.
