> TSVInput that has been proposed in JENA-69 contains two bugs:
> 1) When you attempt to read an empty ResultSet (i.e. a ResultSet that contain 
> no binding) the code will enter in an infinite loop. This issue is really 
> simple to solve.
> 2) Optional binding values are not supported, especially with the following 
> ResultSet:
> (resultset (?a ?b ?c)
>     (row (?a 1) (?c 4))
>     (row (?a 1) (?b 2) (?c 3)))
> it will be serialized as:
> a....b....c
> 1..........4
> 1....2....3
> When we call tokenizer.next(), we get the next token. The problem is that we 
> are not aware that the tokenizer has consumed two separators (\t), and we 
> cannot detect that the value 4 is associated to the variable c.
> Any idea to handle it?
