Personally, I say if a statement continues on a different line, then you should use braces

    //okay
    if (condition) return foo;

    //not okay
    if (condition)
        return foo;

    //not okay
    if (condition) do_foo();
    else do_bar();

In the second case, the else can be considered a continuation. In the first example, there's little chance of confusion or the introduction of an error, in the second and third, that is not necessarily the case.

If it doesn't look/fit well on one line, break it up with braces.

What about:

if((somevar != checkvar((byte)othervar)) & (i != 3)) somefunc();

someotherfunc();

A bit exaggerating, I agree, but not far off from some real-world examples and quite confusing.

Nice, in that case, I might advocate for either somefunc or a function in front of it taking somevar, othervar and i as parameters with early return statements before falling through to the work.. returning a boolean for if they passed through...

I've seen far, far, far worse...
