Expect Ripper.tokenize(code).join to match the original code but it doesn't.

code = %[
<<A + "hello
A
world"
]
eval code # => "ruby\nhello\nworld"
code == Ripper.tokenize(code).join # => false
eval Ripper.tokenize(code).join # => Syntax Error

Other codes that does not match.
"<<A;/a\nA\nb/" "<<A;:'a\nA\nb'" "<<A;%[a\nA\nb]"

IRB fails coloring those codes.
