Position incorrect for Parenthesized expression.

[peterhal]

Given a file containing:

(a);

The absolute position of the AstNode will be 1 (the char index of the 'a').
Expected absolute position to be 0 (the index for the '(').

Contrast this with an array literal which has absolute position set correctly:

[a];

[abort]

Noticed the same problem. It seems that it does not cascade over the whole file and it just always deviates with 1 for parenthesized expressions.

Yes, for example having (a).b(); and extracting function call's target from source string according to node position we got a).b which looks pretty weird.

I'm preparing PR to fix this. We can use constructor with explicit position in Parser#parenExpr(). I'll check if it doesn't brake tests.
