openconnect "either to is duplicate or uid is garbage"

edit

I traced this to a problem in the /etc/vpnc/vpnc-script. This script is different from the default vpnc-script at [1]. It was probably obtained from a Cisco Anyconnect installation (which is what is used in my company). In any case, the problem was extra parameters being passed to the route(1) command. A diff of the changes is below, in case anyone is interested. (The patch will probably not be formatted appropriately, but all the same ...)
