Yes, I tried both, and they don't handle this case correctly. (My
original bug report used add-file-local-variable in the reproduction
instructions.)

Should this be filed as a bug, or should I email emacs-devel about this?
I don't know how to solve it beyond let-binding print-escape-newlines to
t in modify-file-local-variable -- I don't know if this can cause other
problems.
