Subject: bug#15894: 24.3.50; unwarranted horizontal auto-scrolling
Date: Thu, 14 Nov 2013 14:59:09 +0100

From "emacs -Q":
1. M-x toggle-truncate-lines
2. Visit a file with a single long line (say, about 300 characters)
3. Move point to the right until horizontal auto-scrolling take
   place. (note that now the point is centered horizontally in the
   window - ok).
4. Now move the point a bit to the left, but not too much, so that
   horizontal auto-scrolling doesn't happen again, and thereby the point
   ends up in a position closer to the left edge of the window.
5. C-x b C-x b (i.e. display another buffer and then display our buffer
   again).

I observe that the cursor is re-centered horizontally, which IMO is not
TRT.  The cursor should be at the same position it was last time I
displayed the buffer (i.e. where I put it).
