Using the latest vim73, changeset c945fdb34ce3, Wed Aug 04 20:55:44
2010 +0200, the two windows of a vimdiff display can get out of
sync.
To demonstrate the problem, cd to the vim/src directory and execute
this command.
vim -d -N -u NONE -i NONE <(hg cat -r ae22c450546c if_cscope.c) <(hg cat -r
4269a0673478 if_cscope.c)
The results are affected by the size of the changed regions and the
number of lines in the terminal. For this example, I used an 80x24
xterm.
The cursor will be in the upper left corner of the left window.
Type j 6 times and the cursor will move down the window as it
should. Type j again so that the cursor enters the top of the added
lines and observe that the right window scrolls down and is no
longer aligned with the left window. Type k and observe that the
right window scrolls up but is still not aligned. Type k again and
the right window continues to scroll up, one line at a time, until
the cursor reaches the top of the left window, at which point the
two windows are again properly aligned.
