Most of the changes look like small improvements, but some of them make things a little worse and should not be done.

I am not sure that removing the name “pc” makes the code more clear. I would probably leave it in.

Removing the name “destination” makes this less clear.

Removing the names “cell”, “string”, and “storage” here makes this less clear. Those names aren’t redundant.

Ok, I will omit the changes you mentioned above and submit a patch.
