More corrections to CLtL

[Dave <Steiner@BLUE.RUTGERS.EDU>]

I've found several printing bugs in the format chapter.

1) The code on p. 394 to show the scale factor doesn't work.  It
should be something like:

(dotimes (k 13)
  (format t "~%Scale factor ~2D:~:* |~13,6,2,VE|"
          (- k 5) 3.14159))

Ie, Missing % at the beginning and a missing ~:* to back up to the
scale factor again (or add (- k 5) as a third arg in the second
position and don't include the ~:*).

2) The output to this code with scale factor of 7 is missing a 0 after
the decimal point.  Ie.  |3141590.0E-06|, not | 3141590.E-06|.

3) The format expr in the function definition of FOO (on p 396) is
missing a 4th x arg.
