  * 08d6dd6 Improve safety wrt. special characters in tmpfile snippet (Allan Odgaard)

    Previously we would expand the variable immediately and surround the
    expanded variable in single quotes.

    This change delays expanding the variable which removes the need to
    quote it (except for the double-quotes during expansion which indicates
    that it should be expanded as a single word).
