No, the problem I describe is specific to the "refined" diff
highlighting: I rely on this highlighting to tell me what has "really"
been changed, yet it's not applied to lines that are "just added" or
"just removed" so I end up skipping over them unwittingly because they
are highlighted identically to the *unchanged* parts of those lines
which are otherwise changed.
