Key documentation consistency

[Daniel J S. <dan...@ie...>]

The documentation for key indicates:

  The defaults for `set key` are `on`, `right`, `top`, `vertical`, `Right`,
  `noreverse`, `noinvert`, `samplen 4`, `spacing 1.25`, `title ""`, and
  `nobox`.  The default <linetype> is the same as that used for the plot
  borders.  Entering `set key default` returns the key to its default
  configuration.

and when I do the following:

gnuplot> plot x, -x
gnuplot> show key

	key is ON, position: top right vertical inside
	key is right justified, not reversed, not inverted, enhanced and not boxed
	sample length is 4 characters
	vertical spacing is 1 characters
	width adjustment is 0 characters
	height adjustment is 0 characters
	curves are automatically titled with filename
	maximum number of columns is calculated automatically
	maximum number of rows is calculated automatically

	key title is ""

The vertical spacing says 1 character, not 1.25.  Mistake?  Change in 
code without change in documentation?  Also, that space between max rows 
and key setting isn't needed.
