>Why put in series resistors, except to reduce EMI?

The PIC electrical limits spec has a limit on the output current on any
pin. When the caps are discharged the limit is exceeded. This may collapse
my power supply (which is sometimes non-standard) and reset or glitch the
pic (it will recover and try again by watchdog). 220 ohms is a safe value,
I can actually use 110 ohms at 5V.
