Wrong formatting on comment just after a then

[I3oris]

The following code, compile fine:

case :foo
when :foo then puts "foo"
when :bar then # comment
when :baz then puts "baz"
end

But it get formatted like this:

case :foo
when :foo then puts "foo"
when :bar # comment
 then
when :baz then puts "baz"
end

which doesn't compile any more.
=> Error: unexpected token: "then" (expecting when, else or end)

I would expect the code to staying the same.
