Re: The One True Style of indentation:

[Tardis]

It is almost as religious an issue as best editor or where to put the braces...

Brace placement - there is the right way, and then there are the other wrong ways.

:-)

Best editor is of course emacs, since I don't have to care about indenting, I just press tab and emacs moves the cursor to the right place, no matter where on the line the cursor is.

Absolutely. I use

function(arguments)
{
    if (condition)
    {
        ...
    }
    else
    {
        ...
    }
}

Brace placement is far more important to me than indentation, though I use tabs for that with four spaces as my second choice, if, for instance, the tab key breaks or starts printing Ős. That's never happened, but if it did I'd use four spaces and buy a new keyboard. But something like

function(arguments) {
    if (condition) {
        ...
    } else {
        ...
    }
}

is unreadable.

[Aristotle]

Absolutely. If you want to do it right, it would have to look like this:

function(arguments) {
    if (condition) {
        ...
    }
    else {
        ...
    }
}

Makeshifts last the longest.
