It is an implementation detail: to determine the differing words, I turn all whitespace into newlines in that particular hunk, and then run another diff (nested diff run!). So, the space in --- and the newline in +++ compare equal. Since wI am mostly interested in the _new_ (gree) version, the newline is printed, not the space.

Hmmm. I have to think about it.
