[BUG] begin and end match with enum/localparam named END/BEGIN

[alexisfrjp]

Describe the bug
When the cursor is in begin or end, the corresponding other side is highlighted.
It doesn't check the case for that, having an enum/localparam/whatever named END or BEGIN, moves everything.

begin
  case (fsm)
  INIT: begin end
  END:begin end
  endcase
end
