Thanks, this makes sense. POSIX says:

     [description of \n, \r, etc...]
     The interpretation of a backslash followed by any other
     sequence of characters is unspecified.

so we were wrong to rely on an unknown backslash-escape
being left alone. A quick grep seems indicate that this is
the only spot with the problem.
