I think to make up my mind I'd need a few words about each part of the
changes (with the exception of the test suite changes): why is each of
them needed, and what does it do to fix which part of the original
problem.

I also wonder how come we've succeeded to break quoted file names so
fundamentally -- what change did that, and why did we make it on the
release branch?

Thanks.
