Prevent display_and_set_cursor from being called, I presume?
There's also set_cursor_from_row, which calculates where to display
the cursor, and something should be done about that to indicate that
the cursor is not shown at all.

display_and_set_cursor is also called from dispnew.c, so I'm not sure
redisplay_window alone will be enough.
And why only "before window start"? what about beyond window's end?

I think you need to add something to the struct window's 'cursor' and
'phys_cursor' members.

You cannot express coordinates outside of the window as X/Y.
