The way i understand my example is as follows: 1) An user compare current buffer (buf-a) with file-b. ;; buf-a content: boo ;; file-b content: foo ;; they are different: new faces shown their differences. 2) The user update buf-a and perform a new comparison with file-b. ;; buf-a content: foo ;; file-b content: foo ;; same content, but is not obvious because the result of the ;; previous comparison is not removed. My point is: why don't we perform a fresh comparison in 2?
