Must switch instruction be in multiple lines


The langref shows the following. It is in multiple llines. Is there a
way to make it in one line. Or the format requires it to be in
multiple lines.

switch i32 %val, label %otherwise [ i32 0, label %onzero
                                    i32 1, label %onone
                                    i32 2, label %ontwo ]

Have you tried writing it on one line to see what happens? That would
be the obvious first step.
