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.
