Here we go with the voodoo electronics, and a absolute statement for bonus.
So using a "protecting" (whatever that really means) resistor is *always*
better than any other alternative?

I'll have to go back and tell my customer with the high volume
cost-sensitive electronic badge to stop making them immediately because the
design is incorrect.  I'll need to make the PC board a little bigger to fit
all the resistors for the unused PIC pins (we used a 44 pin QFN package even
though a 28 pin PIC was sufficient because the 44 QFN package was smaller
than any 28 pin package for that PIC type), the board will be a bit more
expensive because I'll need another layer or two to route the lines out from
the PIC, and they'll have to make the case bigger too.  I'm sure the
customers will be understanding when the badge is bigger, heavier, and costs
more.  After all, it *always* has to be done this way.  It's not clear
though what exactly these resistor are supposed to be in series with.  A
small piece of dead fish, I presume?  Can you get those in 0402 or 0603
packages?
