[aprssig] PACCOMM TNC & WIDEn-N clarification

I've got an old KPC2 that I've used to experiment from time to time as a
fill in (temp) Digi using the alias of WIDE1-1 (only). That way the only
things I repeat are things that haven't already been Digi'd. Only problem is
that since it can't count down WIDE1-1 to WIDE* it retransmits the signal as
WIDE1-1(or whatever you have in your UNPROTO path). I tried to enter WIDE*
in the UNPROTO path but it wouldn't take the * character. If it works in
your area it's a way to use the old TNC's as a sudo WIDEn-N (Fill IN) Digi.
Would NOT work for a wide area Digi.

Somebody correct me if I'm wrong it's been a long time since I tried this
(as an experiment only).
