Right now, when bundling a bunch of javascript files, each line of source code is prefixed with a tab (see code). This adds quite some extra whitespace (for my project it results in a 4% larger library size). Besides that, my project uses 2-space indentation, so the resulting mix of tabs and spaces for indentation is quite weird.

I'm not sure if anyone prefers this extra indentation, but I would be very happy if webpack would just not add these tabs. Or make it customizable?
