String cutoff error, prevents passing test

I apologize if this a quite obvious mistake on my part, but I have been staring at this for an hour. I don't know how this could possibly be a bug on your end, but it's worth a try.

The following test does not pass:

``` javascript
exports.testWhile = function(test){
test.expect(1);

var input = parseSingleStat("while(foo() < 1){bar();}");
var output = parse("var __t0 = foo(); while(__t0 < 1){bar(); var __t0 = foo(); }");

test.equal(deparse(output), deparse(tacifyFunctions.tacifyWhile(input)));

test.done();

}
```

The following test passes:

``` javascript
exports.testWhile = function(test){
test.expect(1);

var input = parseSingleStat("while(foo() < 1){bar();}");
var output = parse("var __t0 = foo(); while(__t0 < 1){bar(); var __t0 = foo(); }");
var e = deparse(output);
var o = deparse(tacifyFunctions.tacifyWhile(input));

test.equal(e, o);

test.done();

}
```

deparse returns a string. In the former case deparse(tacifyFunctions.tacifyWhile(input)) is returning a string

Here is output from the test

I would appreciate any insight.

阅读 tests/tests.js 中的 testWhile，并运行报告的测试以重现失败。将两个 deparse 调用与显示的预期字符串和实际字符串进行比较；完成意味着确定原因，并通过一个通过的测试确认针对性的修复。
