Thanks for digging. Big thread, not going to re-read it now. I'd just
like to have this.

I think we should aim to keep a 1=1 mapping between range-diff and
log/show options when possible, even though the output might have a
slightly different flavor as my 4th paragraph discussing a potential
--stat talks about.
E.g. I can imagine that range-diff --no-patch --stat --summary would not
show the patch, but a stat as described there, plus e.g. a "create
mode..." if applicable.
This change implements only a tiny fraction of that, but it would be
very neat if we supported more stuff, and showed it in range-diff-y way,
e.g. some compact format showing:
1 file changed, 3->2 insertions(+), 10->9 deletions(-)
create mode 100(6 -> 7)44 new-executable
