I go to quit emacs, or kill a buffer. It has been modified. How can I see what
the changes are? An ediff for this would be nice.
You know what would be great? If when asking whether to save the buffer, emacs
would offer to show the diff.

I like your suggestion.
What I do is "undo" which tends to remind me what / where the buffer got changed. Often it was by accident. And if I want to keep the changes, I redo and then save.

To compare a buffer with the associated file:
M-x diff-buffer-with-file

,----[ (info "(emacs)Save Commands") ]
| `d'
| Diff the buffer against its corresponding file, so you can see what
| changes you would be saving. This calls the command
| `diff-buffer-with-file' (*note Comparing Files::).
