  them from using up all available memory space, garbage collection trims
  them back to size limits you can set.  (For this purpose, the ``size''
  of an undo list measures the cons cells that make up the list, plus the
! strings of deleted text.)  Two variables control the range of acceptable
! sizes: @code{undo-limit} and @code{undo-strong-limit}.
  
! @defvar undo-limit
  This is the soft limit for the acceptable size of an undo list.  The
  change group at which this size is exceeded is the last one kept.
! @end defvar
  
! @defvar undo-strong-limit
  This is the upper limit for the acceptable size of an undo list.  The
  change group at which this size is exceeded is discarded itself (along
  with all older change groups).  There is one exception: the very latest
! change group is never discarded no matter how big it is.

  This is the upper limit for the acceptable size of an undo list.  The

! @end defopt

! @defopt undo-outer-limit
! If at garbage collection time the undo info for the current command
! exceeds this limit, Emacs discards the info and prints a warning
! message.  This is a last ditch limit to prevent memory overflow.
