cvs commit: fptools/libraries/base/GHC Read.lhs

[Simon Peyton-Jones]

This is most odd.  Why on earth does Haskell 98 lex
have the equation
	lex "" =3D [("","")]

rather than
	lex "" =3D []

After all, "" isn't a lexeme. =20

What would break if I proposed to change the H98 equation?

(Asking a small group first.)

Simon
