Bug: parentheses are removed when converting `+` expressions

[Marnen Laibow-Koser]

JavaScript input:

var x = 5;
'Chapter ' + (x + 1);

(returns Chapter 6)

Expected CoffeeScript output:

x = 5
'Chapter ' + (x + 1)

Actual CoffeeScript output:

x = 5
'Chapter ' + x + 1

(returns Chapter 51)

The issue here is that + is overloaded in JavaScript to have different semantics with numbers and strings. If all operands are of one type, then parentheses don't matter, but when both numbers and strings are involved, the values are converted at different times, leading to different results depending on parenthesization.

It's been over a month with no response. Any update? Do you need more info or help from me?

I just stumbled over the very same issue. Those parens are important.They shouldn't be removed.
