Yes - a deliberate change, and one which I'm going to review, as it does
affect this usage to discover rat connections. There may be a better
compromise than reverting the previous behaviour.

User-error (by me) caused the mistake, but the connectivity scan in PCB
was not very helpful in discovering the problem!

That would not solve the issue. The problem I was trying to deal with
relates to misleading output when hitting "F" on some copper belonging
to a net which contains a short to a different net.)

The "F" tool would proclaim that completely isolated copper areas were
connected. Our short-handling is not very good at the moment!



I'll aim to have this fixed in a more agreeable fashion before our next
release.
