Comment on Never create Ruby strings longer than 23 characters parent

The length is stored in a flag.

include/ruby/ruby.h:

    #define RSTRING_EMBED_LEN(str) \
         (long)((RBASIC(str)->flags >> RSTRING_EMBED_LEN_SHIFT) & \
                (RSTRING_EMBED_LEN_MASK >> RSTRING_EMBED_LEN_SHIFT))

    #define RSTRING_LEN(str) \
        (!(RBASIC(str)->flags & RSTRING_NOEMBED) ? \
         RSTRING_EMBED_LEN(str) : \
         RSTRING(str)->as.heap.len)
