Due to Javascript don’t need to have semicolon at end of statement there are times when the parser thinks the line continues on the next line.
For example we have a file.js:
var f = function(x)
{
return x + x;
}
Now in another file we do:
#include file.js
(function(exports) {
a = 42;
})(exports.b)
There will be two different behaviors if the ’file.js’ has a semicolon at the end of the last line. This commit make sure we have the right behavior.
