Other backward incompatibilities:

  - 'a''b'  changes from meaning "ab" to meaning "a'b"

  - backslash-newline within quotes changes from meaning a literal
    newline to meaning an empty string.

  - lexer.m gives an error for an unrecognized escape sequence within a
    quoted name (lexer__get_quoted_name_escape), whereas mdb always
    inserts the character literally.  I don't think it very important
    what behaviour we have for unrecognized escape sequences.  I'd keep
    mdb's behaviour just for ease of implementation.
