I assume the reason is that "git diff tree1..tree2" works with the
differences between tree1 and tree2, much like "git log tree1..tree2"
does.  On the other hand, "git log tree1 tree2" is something
completely different.

So at least in my mental model, it's "git diff tree1 tree2" that's out
of place, not really the one with the range specifier.

Apparently what's intuitive to one person isn't always intuitive to the next.
