Reimplement intern-concat to accept only strings and symbols as string designators.
Reimplement intern-concat to accept only strings and symbols as string designators.

Simply using PRINC can have different semantics on different
lisps. Explicitly allowing only strings and symbols resoles this issue
and makes clearer what inter-concat is intended to deal with. (passing
objects or numberns to inter-concat was never intentional anyway).
