I don't think this is true.  I don't have the instruction set in front of
me, but I *think* that INCF modifies the Z bit regardless of the result.  In
other words, when you use INCF and don't overflow past zero, the STATUS, Z
bit will be cleared.  You don't want this to happen because you aren't
saving W or STATUS anymore in your ISR.

I would highly recommend using INCFSZ just in case, plus it only adds one
extra RETFIE instruction at the end of the ISR routine.
