+ @defvar line-spacing
+ When this permanently buffer-local variable is non-nil, if its value is
+ an integer, that many pixels of extra space are put below each line.  If
+ the value is a floating point number, compute the spacing by multiplying
+ the value by the default frame line height.
+ 
+ Note that this variable and the frame parameter @code{line-spacing}
+ (described above) control different things.  The frame parameter is
+ involved in setting the frame line height (@pxref{Creating Frames}),
+ while the buffer-local variable is for already-created frames.
+ 
+ For example, if the frame parameter is nil, a variable value of 1.0
+ ``double-spaces'' the display because for every line of text, there is
+ an additional full line of space put below it.  Likewise, a value of 2.0
+ ``triple-spaces'' the display, and so forth.  If, on the other hand, the
+ frame parameter is 10, a variable value of 10 would effectively put 20
+ pixels of space under the text.

  @defvar blink-cursor-alist
  This variable specifies how to blink the cursor.  Each element has the
  form @code{(@var{on-state} . @var{off-state})}.  Whenever the cursor
