I set them as outputs driving low and leave them disconnected because:

1  -  It is easier to make a manual change to use a pin if it is not
connected to anything.

2  -  A firmware bug won't accidentally cause a lot of current draw thru the
pin.

3  -  Driving low by default is better than driving high because this works
for open drain outputs too.

My PIC assembler preprocessor and the PORT module automatically set all
unused pins as outputs driving low.  See the /INBIT and /OUTBIT directives
in PREPIC and the PORT module at http://www.embedinc.com/pic.
