    # When passing arguments to native commands, quoted segments that contain
    # spaces need to be quoted with '"' characters when they are passed to the
    # native command (or to bash or sh on Linux).

    # to the testexe native command and looking at how it got the arguments.

    # In order to pass '"' characters so they are actually part of command line
    # arguments for native commands, they need to be escaped with a '\' (this

    # PowerShell).

    # This functionality was broken in PowerShell 5.0 and 5.1, so this test
    # will fail on those versions unless the fix is backported to them.

    # passing arguments with escaped quotes to the testexe native command and
    # looking at how it got the arguments.
