I have to disagree on this part, as much as commenting is not really required, leaving the authors name on a specific section if they've created it should be ok, that way they can get some attention and gratitude for the work they've done and not be generalized as simple "dev".
The do nothing example of course is although incorrect because it should be does nothing, but aside from that I agree with it.
However I wouldn't mind if behind
getitem 601,1;
there was
getitem 601,1; //apple
, now the example is silly because everybody knows 601 is an apple but, not everybody knows that 12103 is a bloody branch.
As to indenting, I know I personally don't use it too much when I'm on a script spree because I know what I'm doing, but I have to agree with it's usage, it makes things easier for everybody else and therefore I support it, however anything that's in a comment should be up to the author, one could go through each script and change it but that would simply be aesthetic and not required as it isn't required to be read anyways so why make it pretty.
