Yeah. This has been the documented behavior for quite some time, but
I can't say that I ever liked it.

I think that suppressing unquoted trailing whitespace is probably
reasonable. I'm much less enthusiastic about rejecting unquoted
embedded whitespace, though. I think that's significantly likely
to break apps, and it doesn't seem like it's really needed to have
sane behavior. The leading/trailing whitespace asymmetry is just
weird, but it doesn't follow that embedded whitespace is weird.
If we are going to make such changes, 8.0 is the right time to do it.
