Broken if/else blocks

[NeilWhitworth]

if/else blocks get a new line character added incorrectly, causing some browsers to fails with 'Unexpected strict mode reserved word'

This input javascript
if (true) {
console.log('in if');
} else {
console.log('in else');
}

results in this minified block
;if(!0){console.log('in if')}
else{console.log('in else')}

instead of
;if(!0){console.log('in if')}else{console.log('in else')}
