Shrinksafe handles unary "+" operator incorrectly

[ppedemon]

Shrinksafe doesn't handle unary plus operator correctly. For example, the following snippet:

var dummy = 1 + +2;
console.log(dummy);

Is turned into this (keeping original var names):

var dummy = 1++2;
console.log(dummy);

That's not legal Javascript syntax, so when executing Shrinksafe's output, you'll get an "Invalid increment operand" syntax error.

You can argue that no one writes code like this (in fact, my extra "+" when I discovered the error was a typo), but unary plus is legal javascript after all.

NB: I'm reporting for Dojo 1.1.0, but it might be present in newer versions as well.

(In [20178]) Cover case with adjoining sub and neg operators as well. Refs #9676

shrinksafe.jar file didn't updated for this change.
