[PD] pduino test patch: "old analog/digital controls"

due to the pduino rewrite I've to reanimate this threat ;)
I would like to remove the ambiguity and confusion about this old and new way of enabling the analog pins.
old way of enabling the analog 0 pin is sending the following to the arduino object:
[analogIns 0 1(
enabling the same pin(analog 0) the new school way:
[pinMode 14 analog(
is this correct? if so what's a bit byte confusing for people is that in the new way pin 14 equals the analog 0 pin -
guess this is a peculiarity of firmata? isn't there a possability to use f.e. A0-A5 for adressing the analog pins?
thanks for info & salutis
