To state it explictly, in the absence of the "extra" indentation
this would be formatted

    while (this_is_true
	   && that_is_not_false) {
	frobit();
	more_stuff();
    }

which is, as was noted, quite readable for the while() case, and
only if() has trouble.

And for this specific case, I am used to the rule being that if you
break mid-function-call, you indent to the paren for the function
call, as in

    if (some_long_text && foo(a,
                              b, c) && bar()) {

which rather inherently incentivizes not breaking across the
function call.

I read the rest of the thread and don't really have more to add to
it.
