I think the issue might be: buffer-undo-list has an element of the form: (t 0 0 0 -2000) I don't know where -2000 picosecs comes from. In undo.c, the test was: EMACS_TIME_NE (mod_time, base_buffer->modtime) Now the test is: (equal time (visited-file-modtime)) But visited-file-modtime returns 0 rather than -2000 picoseconds.
