DecimalFloat

The documentation currently describes DecimalFloat as:

DecimalFloat:
	DecimalDigits .
	DecimalDigits . DecimalDigits
	DecimalDigits . DecimalDigits DecimalExponent
	. DecimalDigits
	. DecimalDigits DecimalExponent
	DecimalDigits DecimalExponent

I believe this is incorrect.  It should be, by my reasoning:

DecimalFloat:
	DecimalDigits .
	DecimalDigits . DecimalDigits
	DecimalDigits . DecimalDigits DecimalExponent
	. Decimal
	. Decimal DecimalExponent
	DecimalDigits DecimalExponent

The reason I believe this to be is simple.  Try the following code:

writefln(._1);

According to the previous definition of DecimalFloat (as far as I read 
it), that should be equivalent to:

writefln(.1);

However, it instead generates an error with DMD.  I think this makes the 
most sense, and serves to clarify that this:

writefln(._);

Is also not a FloatLiteral (which I think is pretty clear.)
