qr/\p{pkg1::...foo}/ must be a user-defined property
So, if it isn't found and 'foo' doesn't begin with 'In' or 'Is', we know
that there would be a run-time error, which we can fail with at
compile time instead. We use a different error message than if we don't
know if it is a user-defined property.

I didn't make a perldelta entry, as I doubt that this has ever come up
in the field, as I discovered the issue myself while playing around
investigating other bugs.
