For what it's worth, on just an ordinary two line string (with an escaped
EOL), if the first line is commented out (and the backslash deleted), the
two quote marks also match eachother for C-M-f and C-M-b.  So I agree
with you, this isn't such a big problem in raw strings.

Thanks for the testing.  I've now pushed the changes (to both savannah
master and CC Mode's c++11-0-1 branch), but if anything more comes up, I
can correct it.
