I’m sorry if I misunderstood you. I’m indeed interested in what from all you wrote is then what you would suggest to be changed, as I also looked at his code and also read here that it was done in short time so I also believer there are possibilities for improvement. Specifically, reimplementing sha calculation itself should be a non goal, in my opinion. Just that the .sh code itself works on all POSIX shells, not that the whole system has to be POSIX only: calculating sha in shell is surely not the point of demonstrating how git works.
