Missing redraw when changing 'ff'

[Ben Schmidt]

Hi, Bram,

I'm getting back into doing some Vim coding, and mailing list
interaction and so on, and have come across this old patch (attached;
originally on vim_use).

The changes to ex_cmds.c are obsoleted by patch 7.2.082, but the change
to option.c is still relevant.

The problem is that when 'ff' is changed, the screen is not redrawn, so
any ^J or ^M in the buffer are incorrectly displayed until you scroll or
redraw.

Ben.

between "unix" and "dos" and don't need a redraw.

Yes, that would be better. Mac line endings are rare, and becoming
rarer.

Mind you, changing 'ff' is pretty rare in itself. Plenty of other things
trigger redraws that happen a lot more often.
