    Use new cc-mode multiline support for normal strings
    
    c-multiline-string-start-char was the previous way to handle multiline
    strings. cc-mode has replaced this by with c-ml-string-opener-re and
    c-ml-string-any-closer-re. This is now used for handling normal
    strings in D since all normal strings can be multiline.
