Can we use a parameter to choice a delimiter?

[jrichardsz]

I used this library to join js files. Works but does not apply a kind of separator or delimiter. In my case I need a simple \n, because without that I have this error:

In this case, If I could use \n as delimiter, this will be the expected result:

/*file1*/
!function(t){"use strict";"function"==

/* file2
