Just to have this information here for easy access, this is upstream's
response from that bug's URL [1]. They recommend "rsync or something else":

    The scp command is a historical protocol (called rcp) which relies
    upon that style of argument passing and encounters expansion
    problems. It has proven very difficult to add "security" to the scp
    model. All attempts to "detect" and "prevent" anomalous argument
    transfers stand a great chance of breaking existing workflows. Yes,
    we recognize it the situation sucks. But we don't want to break the
    easy patterns people use scp for, until there is a commonplace
    replacement. People should use rsync or something else instead if
    they are concerned.
