set default arguments for processFinalOperand()

with the new translator routines, processFinalOperand() will mostly be
called with only a single token pointer; the second token and operand
index arguments are only used for operators (internal functions and
parentheses tokens in old translator only); the number of operands
argument is also only used in the old translator
