Incorrect brace syntax highlighting within switch case

[dklilley]

Consider the following code:

switch input
    case 0
        disp foo
    case { 1,2}
        disp bar
    case {3,4 }
        disp foobar
    case {5,6}
        disp baz
end

Because of the space after the 4, the tokenization of the {3,4 } is incorrect. This causes the following case to be tokenized incorrectly as well.
