dropbear: dbclient.1 annotate

annotate dbclient.1 @ 1933:e093ddc5b585

Fix extra default -i arguments for multihop When multihop executes dbclient it should only add -i arguments from the original commandline, not the default id_dropbear key. Otherwise multiple -i arguments keep getting added which results in servers disconnecting with too many auth attempts
