12.8.3 Retrieving Old Revisions
You can use the command C-x v ~ (for vc-version-other-window) to retrieve any saved revision of a file. The revision is retrieved into a work file with the same name as your file, except for a suffix that identifies its revision number (the suffix is actually a dot, followed by a tilde, followed by the revision number, followed by another tilde). So you can retrieve several revisions, and they won't step on each other. This command is useful when you want to eyeball the entire old version of a file, as opposed to just its changes from previous versions or its differences from later ones.
The version suffix format is very close to what Emacs generates for saved versions if you set the global Emacs Lisp variable version-control (which VC has made pretty much obsolete). For example, if you're visiting a file named foo.html and you retrieve version 1.3 by typing C-x v ~ 1 . 3 Enter, you will now be visiting a file named foo.html.~1.3~ (and because it ends with a tilde, Dired's command to flag backup files will mark it, as discussed in Chapter 5).
