Spurious "" passed as argument to triplequote macro?

[Scott Jones]

I'm trying to revamp the `triplequote` code, used by the special `m_str` macro to handle """,

however, it seems to be getting passed an extra argument, and I wondered if that was expected...

Julia> z = """
           $s
           $s"""
Any["\n    ",:($(Expr(:escape, :s))),"\n    ",:($(Expr(:escape, :s))),""]

 Thanks!
