The difference between k-- and k-1 may be in the resulting code the
compiler creates.  k-- would automatically create a DEC <reg> type of
instruction while k-1 would create a SUB <reg>,<value>  where "reg" is
a register (or memory address) and "value" would be 1.  Though I would
think a compiler that does a decent job of optimization would automatically
turn any SUB ,1 's  into DEC's, but you never know.
