Package: emacs
Version: 24.0.50
X-Debbugs-Cc: eliz <at> gnu.org


   emacs -Q

then evaluate

  (setq scroll-conservatively most-positive-fixnum)
  (setq-default bidi-display-reordering t)

to use line-by-line scrolling.

Then C-x C-f abbrev.el, and press <down> until the cursor reaches the
^L at line 73.

The buffer is suddenly recentered. Moreover, if you then move up the
cursor to just after the ^L and press <left>, the cursor jumps to the
end of the first line in the window.

There was a general problem with lines that end in glyphs from display
tables.  Should be fixed now (revno 100417).
