Unlike ediff-buffers, diff-buffers always compares the entire buffer
contents, not the accessible portion.  I think it would be better to
restrict the diff to the accessible portion, since normally buffer
commands only act on the accessible portion (and the capability to
compare only portions of buffers is occasionally quite useful!).  IIUC
the only change needed would be to replace (write-region nil nil ...)
in diff-file-local-copy with (write-region (point-min) (point-max) ...).
If we don't want to change the default behavior, then this could be made
configurable with a customization option.
