Small semicolon inconsistency fix for some minifiers

[funkynicco]

There is a missing semicolon for the variable declarations on lines 124-131 (as of current date of writing this, latest commit being e7444c9).

This breaks some minifiers which makes the minified code as following example:

var x=function(){}if(!y)

This generates "unexpected if".

If anyone is able to fix this it would be great (theres a number of minifiers that does not build up an AST syntax tree to determine what the code actually does).

If figured opening an issue on the matter is less effort overall than forking and doing a pull request for a very tiny fix.

Thanks.
