You're right, of course.  Looks like either a bug in the program, or
incorrect documentation (the one sentence there is).  (A copy of this is
going to Protel support.)

On Design | Rules | Other, "Un-connected Pin Constraint" says "Detects pins
that have no connecting tracks."  There's no mention of it mattering whether
or not the pin is listed in a net.  Also, the help file does not document
this rule at all. (It does list the other 2 rules on the "Other" tab.)

I hope Protel support will comment on what they believe this rule is

Subject: Re: [PEDA] single pin nets

I tried that, it finds all unconnected pins (which I have a lot of) and
did  not find a named net with only one connection (just a net name on only
one unused pin).  The single pin net does appear in the netlist (generated
from the pcb), so it isn't flagged as an unconnected pin.
