whitespace differences from endo bundler

[erights]

just capturing some discrepancies as I notice them during a debug session.

Btw, I was not able to get into the debugger by setting a breakpoint on the source file. So instead I edited in a debugger;, whereupon I saw the bundle file and can set breakpoints in it. What do we need to do so that breakpoints on the original source work? Is this possible?

On the second example, notice the difference in parens. Does babel prevent us from preserving the parens from the original source?

@kriskowal should one of these be closed as a dup of the other?
