0. emacs -Q
1. Set auto-hscroll-mode to `current-line'.
2. Visit a buffer that uses tabulated-list-mode, e.g. Buffer Menu (C-x
   C-b), Package Menu (M-x list-packages), Proced (M-x proced), making
   sure that the buffer contains at least one truncated line and a line
   below it.
3. Advance point along the truncated line (e.g. by repeating C-f or M-f
   or with C-e).
=> When point gets within hscroll-margin columns of the right window
   edge (or further), instead of the current line being scrolled, the
   one below it is.

(In addition, with Proced, the header line is also scrolled, but that
seems to be a Proced bug, since that also happens when auto-hscroll-mode
is set to t; and with Buffer Menu or Package Menu the header line does
not scroll with either setting of auto-hscroll-mode.)
