@deffn Command auto-save-mode arg
-When used interactively without an argument, this command is a toggle
-switch: it turns on auto-saving of the current buffer if it is off,
-and vice versa. When called from Lisp with no argument, it turns
-auto-saving on. With an argument @var{arg}, it turns auto-saving on
-if the value of @var{arg} is @code{t}, a nonempty list, or a positive
-integer; otherwise, it turns auto-saving off.
+This is the mode command for Auto Save mode, a buffer-local minor
+mode. When Auto Save mode is enabled, auto-saving is enabled in the
+buffer. The calling convention is the same as for other minor mode
+commands (@pxref{Minor Mode Conventions}).
+
+Unlike most minor modes, there is no @code{auto-save-mode} variable.
+Auto Save mode is enabled if @code{buffer-auto-save-file-name} is
+non-@code{nil} and @code{buffer-saved-size} (see below) is non-zero.

@defun auto-save-file-name-p filename
After Emacs reads your init file, it initializes
@code{auto-save-list-file-name} (if you have not already set it
non-@code{nil}) based on this prefix, adding the host name and process
-ID. If you set this to @code{nil} in your init file, then Emacs does
+ID@. If you set this to @code{nil} in your init file, then Emacs does
not initialize @code{auto-save-list-file-name}.
