Most buffers have an @dfn{undo list}, which records all changes made
to the buffer's text so that they can be undone. (The buffers that
don't have one are usually special-purpose buffers for which Emacs
assumes that undoing is not useful.) All the primitives that modify the
assumes that undoing is not useful. In particular, any buffer whose
name begins with a space has its undo recording off by default,
see @ref{Buffer Names}.) All the primitives that modify the
text in the buffer automatically add elements to the front of the undo
list, which is in the variable @code{buffer-undo-list}.
