I am concerned we are going to generate confusing if we warn about one
use of backslashes in strings but not another. I am thinking we will
just add the infrastructure for E'' in 8.1 (with the warning turned
off), and state we will warn about all backslashes in non-E strings in
8.2, and maybe go for literal strings in 8.3 or 8.4 depending on user
feedback.
