another minor fault in the Haskell Report

[Simon Peyton-Jones]

Thanks.  Fixed.

Incidentally, the cement is set just about solid.  I've had no
substantive bug reports since the June release, so I'm on the
point of declaring the H98 Report finished.  I'm just waiting for
a few hours spare to do some cosmetics. =20

(This message is a genuine bug, but I'm not resetting the clock!)

|     instance Read Double where

| are incorrect because they do not deal with a leading minus=20
| sign. The correct versions are:
|=20
|     instance Read Float where
|         readsPrec p =3D readSigned readFloat
|     instance Read Double where
|         readsPrec p =3D readSigned readFloat

| Funnily enough, all the implementations seem to have this fix=20
