Bug report

Bug description:

There is a bug in the new repl syntax highlighting when using pattern matching with cases spawning across new lines.

To reproduce:

def status(code):
    match code:
        case 0: return "OK"  # correct highlight
        case -1:                      # correct highlight
            return "Error"
        case -2:                     # no highlight
            return "Big Error"
        case _:                       # no highlight
            return "Unknown status"
