Well, if you are in a file with lots of lines both above and below the
cursor, then ":set so=999" (or some other big value) should keep the
cursor near the middle of the window. However:

* It is not possible to make the first line in the file start lower than
the top of the window.

* When 'wrap' is on, the top of the window will always be at the start
of a line (which may occupy several lines on the screen), except perhaps
if the current line is bigger than the whole window (in which case
either or both of the start and end of the current line may overflow the
boundaries of the current window).

* When near the bottom of the file, Vim will let the cursor go down once
the last line in the file is fully inside the window (i.e., 'scrolloff'
doesn't count anything after the last existing line in the file).

Best regards,
Tony.
