Yes, you're right on all counts. So.... what's confusing? :-)

You may expect that because that's what make has printed in the past,
but that's not the correct result according to the POSIX definition of
make.
Please see the NEWS file, or the GNU make manual (the version provided
with beta3 of course).

This is correct.

Right. Did you look up that bug and the accompanying commentary on
Savannah?

Why does it look broken? Run the same command in a (POSIX) shell and
you'll get the new behavior, not the old behavior:
$ echo 'line1\
> line2'
line1\
line2
So, why is it broken that when make invokes a shell to run that same
command you get the same result?

Yes... it's a change that was made so that GNU make would conform to the
POSIX specification for make. Unfortunately, that involves an
incompatibility.
Again, the NEWS file has info about this and other user-visible changes;
it should always be the first place you look when upgrading versions of
GNU make.
