No, this is not rare (Emacs seems to be confused on files that have several encodings, such as mailboxes) and I sometimes hit Ctrl-C in the terminal (from which Emacs was started) to discard any change. And that's not OK to only leave the backup file, since it can be removed or overwritten pretty quickly, before I notice that the original file is gone. In such a case, I would lose the entire file. But why isn't the backup done just before the file is actually written? BTW, I notice that Bug#13522 doesn't occur when the file is in a sshfs directory. -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
