Have you measured the amount of time saved by minification vs. simply concatenating the files? I would guess that the big win is in concatenation, but I don't know for sure.

Regardless, if we want Brackets to work reasonably well in the browser, pursuing minification is likely worthwhile and as long as we don't need *too* many hacks like this, it seems reasonable.

(tangential aside: I've also wondered about us using Closure Compiler on our code, more for type checking than minification. It would be interesting to know if Closure Compiler does this same optimization. Of course, Closure Compiler is written in Java which is something of a drag.)
