It is valid, though. See the POSIX specification:
The <backslash> shall retain its special meaning as an escape
character (see Escape Character (Backslash)) only when followed by one
of the following characters when considered special:
$ ` " \ <newline>
So, this should simply work. It worked on ash before. It also works on
every other POSIX shell, and existing scripts rely on it.
