DMD response files use the same escaping syntax as the 
CommandLineToArgvW function.

Here is how rdmd constructs the file:
https://github.com/D-Programming-Language/tools/blob/master/rdmd.d#L367

I had looked at the DMD code, although it was a while ago and 
today I honestly couldn't say anything specific about it today. 
That's probably still not good enough for a clean-room 
reimplementation, though.
