Indeed that's just stupid.  Making the context lines green or whatever
would make them stand out over the changed lines, which is _precisely
the opposite_ of what we want to do.

On a high-color display (like X11, usually), we can dim the context
lines, and so achieve our goal of making the changed lines stand out
while keeping them in the normal default face; the latter point,
however, is _not_ the main goal!  On a low-color terminal, we often
simply don't have the flexibility to do those two things at the same
time; in such a case, we must discard the less important guideline,
and pick something which at least makes the important lines stand out.
  The current dark-background colors achieve this, and should not be
