`uglifyjs -b` could do a better job with if/else-if/else formatting

uglify-js@2.7.5:

$ echo 'if(x)foo();else if(y)bar();else baz();' | uglifyjs -b
```js
if (x) foo(); else if (y) bar(); else baz();
```
Would be nice to see the following:
```js
if (x)
    foo(); 
else if (y) 
    bar(); 
else 
    baz();
```
or perhaps this since the logic simpler - just make elses always go on next line?
```js
if (x) foo(); 
else if (y) bar(); 
else baz();
```
