Oh. I misunderstood this question at first. I guess it is possible, but it is not likely, for someone to explicitly set `AlwaysBreak` or `BlockIndent` together with `AlignAfterOpenBracketBreak = {false, false, false}`. It's a conflicting set of options in some way. It could be documented as invalid?
