Merge #187: Remove unnecessary borrow

9815a4c Remove unnecessary borrow (Tobin C. Harding)

Pull request description:

  Clippy emits various errors of form:

    error: this expression borrows a value the compiler would
    automatically borrow

  As suggested, remove the unnecessary borrow.

  FTR, this error shows up because of a clippy update (I believe).
