6th writing of insertion sort

Good again.

What did I get though by such repetition?  Now it starts to be the tidbits.  Every statement has a meaning, has a why.  You also want to think about the variations of the algorithm. 

What if it is zero-based index?  What if one makes a mistake in a certain symbol?  What if one change the order of the code?

How to improve it? How to improve in a certain language?
