Tab-complete error with pkg mode

[jakobjpeters]

To reproduce, enter package mode and type a;[TAB]. Uncertain if it's related, but sometimes you can type ; in package mode and it will stay in package mode, rather than switch to shell mode. In this case, entering [TAB] throws the same error as with a;[TAB].
