* src/move.c (do_down) - Correctly compute the minimum amount
to scroll when softwrap is on and there are overlong lines.
* src/winio.c (edit_scroll) - Disable amount computation here.
* src/move.c (do_down) - Trim some redundant code, and correct
the scrolling behaviour when softwrap is off -- the construct
(amount ? amount : 1) wasn't doing what I intended.

* global.c (shortcut_init) - fix an issue with the split
