code cleanup in druntime and phobos

[Dicebot via Digitalmars-d]

I agree with Iain, we should respect opinion of people trying to 
stay away from intrusive ecosystems like GitHub. While 
probability of someone picking the patches and proceeding with 
them is low (and we shouldn't give false hopes) there is no place 
for "GitHub or GTFO" reaction. It is just rude.
