When auto-hscroll-mode is set to `current-line' and scroll-left is
invoked with arguments ARG > 0 and SET-MINIMUM non-nil, then when the
current line is automatically horizontally scrolled, all other lines in
the buffer are scrolled back to logical BOL, i.e. SET-MINIMUM is ignored
(except on the current line). To reproduce:
0. emacs -Q
1. Set auto-hscroll-mode to `current-line'.
2. Type `C-x C-f /path/to/hscroll-bug RET' (the attached file).
3. Type `M-x toggle-truncate-lines' and `M-: (scroll-left 32 t)'.
4. Type `C-p' repeatedly.
=> When point is on the third line, and for all subsequent vertical
motion, all lines but the current one are displayed starting at BOL
instead of column SET-MINIMUM.
(I found this bug because I sometimes use scroll-left with non-nil
SET-MINIMUM in the Gnus *Summary* buffer to see more of the article
Subject lines; the attached file hscroll-bug, used in the above recipe,
is taken from such a buffer.)
