Does that really need its own article on a vanity blog?

Of course, AS IT DOES NOT WORK FOR OVER 4 YEARS NOW.
A solution, I mean a very ugly band-aid is to change the Arduino IDE formatting config file by hand.
EVERY FUCKING TIME YOU UPGRADE YOUR IDE.

The Auto Format indentation is set in
{Arduino IDE installation folder}/lib/formatter.conf
Change the indent=spaces=2 entry to your liking.

And chill out man.
