null is rendered at the first line in JS when header field is left blank

[jepsar]

When I enter something like // in the header field, it is reflected on the first line.

Might relate to #14

Hey @jepsar can you please be more specific and maybe give a code sample? Will check it. Thx. I moved from YUICompressor to googl closure compiler. Maybe it will be fixed due to the switch but, to less information for that.

Test code:

// Test.

Output:

'use strict';

So I couldn't see any problems here, only that it will always added use strict, but this will be another issue. So it seems to be fixed in 2.4.0.
