bug#61396: diff mode could distinguish changed from deleted lines

[Samuel Wales]

i'm not sure that will work with alternate presentatin f difflll.
what woul dbe good is for the internal diffing to notate not merely
additions and deleteions but also absence of addionts.  a marker that
something will be deleted. no matter where.
