Yeah, I frequently run into this, too, and have just gotten good at
editing the patch. :)
I think splitting line-by-line, as you suggest, would be more general.
However, working within a single cluster of lines is difficult (both
line-by-line and in your whitespace example), because you have to
correlate removed and added lines. E.g., the diff for your change above
might look like:
@@ ... @@
We would want to end up with three hunks:
but how do we know which preimage lines correspond with which postimage
lines? You can probably come up with heuristics for this case (e.g.,
introduced whitespace gets its own hunk, and then count postimage lines
from each end), but there are many harder cases.

If you do (or Junio does), I think the commit message needs a slight

I don't set color.diff.func myself, but having just looked at it when
playing with your patch, I think it looks nice (I did "yellow").
I also set color.diff.meta to "magenta", which I think makes the hunk
header stand out a bit more.
So yeah, I'd be fine with proposing changes to the default color scheme,
though I do not envy you the inevitable bikeshed war. :)
