  *  call-seq:
- *    byteslice(index, length = 1) -> string or nil
- *    byteslice(range)             -> string or nil
- *
- *  Returns a substring of +self+, or +nil+ if the substring cannot be constructed.
- *
- *  With integer arguments +index+ and +length+ given,
- *  returns the substring beginning at the given +index+
- *  of the given +length+ (if possible),
- *  or +nil+ if +length+ is negative or +index+ falls outside of +self+:
- *
- *    s = '0123456789' # => "0123456789"
- *    s.byteslice(2)   # => "2"
- *    s.byteslice(200) # => nil
- *    s.byteslice(4, 3)  # => "456"
- *    s.byteslice(4, 30) # => "456789"
- *    s.byteslice(4, -1) # => nil
- *    s.byteslice(40, 2) # => nil
- *
- *  In either case above, counts backwards from the end of +self+
- *  if +index+ is negative:
- *
- *    s = '0123456789'   # => "0123456789"
- *    s.byteslice(-4)    # => "6"
- *    s.byteslice(-4, 3) # => "678"
- *
- *  With Range argument +range+ given, returns
- *  <tt>byteslice(range.begin, range.size)</tt>:
- *
- *    s = '0123456789'    # => "0123456789"
- *    s.byteslice(4..6)   # => "456"
- *    s.byteslice(-6..-4) # => "456"
- *    s.byteslice(5..2)   # => "" # range.size is zero.
- *    s.byteslice(40..42) # => nil
- *
- *  In all cases, a returned string has the same encoding as +self+:
- *
- *    s.encoding              # => #<Encoding:UTF-8>
- *    s.byteslice(4).encoding # => #<Encoding:UTF-8>
+ *    byteslice(offset, length = 1) -> string or nil
+ *    byteslice(range) -> string or nil
