+You can use `diff-refine-hunk' to see what the actual changes are.\r
+\r
+Try this:\r
+\r
+  #+begin_src emacs-lisp\r
+    (global-set-key (kbd "C-c /")\r
+                    (lambda()\r
+                      "Refine display of unified diff hunks"\r
+                      (interactive)\r
+                      (save-excursion\r
+                        (goto-char (point-min))\r
+                        (while (re-search-forward\r
+                                diff-hunk-header-re-unified\r
+                                nil t)\r
+                          (diff-refine-hunk)))))\r
+  #+end_src\r
+\r
+Work pretty much *anywhere*.\r
+\r
+Note: it does NOT work in `notmuch-show-mode' (not even with\r
+`notmuch-wash-convert-inline-patch-to-part' disabled), but this is\r
+easily solved by first running `notmuch-show-view-raw-message' ("V")\r
+and `diff-mode' (to fontify the buffer)...\r
