Incorrect formatting and lost comments for module without braces

[raffaeler]

When a module is declared without parameters, the file is incorrectly formatted and the comments for the parameters are removed.

Original source to format

`timescale 1ns / 1ps
module stimulus;
    // Inputs
    reg[1:0] x;
    reg[1:0] y;
    // Outputs
    wire z;
    // Instantiate the Unit Under Test (UUT)
    comparator2bit uut (
    .x(x),
    .y(y),
    .z(z)
    );
    
    initial begin
        $dumpfile("test.vcd");
        $dumpvars(0,stimulus);
        // Initialize Inputs
        x     = 0;
        y     = 0;
        #20 x = 1;
        #20 y = 1;
        #20 y = 3;
        #20 x = 3;
        #20 y = 1;
        #20 y = 0;
        
        #40 ;
        
    end
    
    initial begin
        $monitor("t = %3d x = %2b,y = %2b,z = %d \n",$time,x,y,z,);
    end
    
endmodule

Format result without braces:

`timescale 1ns / 1ps
module stimulus; reg[1:0] x; reg[1:0] y; wire z; comparator2bit uut (.x(x), .y(y), .z(z));
    
    initial begin
        $dumpfile("test.vcd");
        $dumpvars(0,stimulus);
        // Initialize Inputs
        x     = 0;
        y     = 0;
        #20 x = 1;
        #20 y = 1;
        #20 y = 3;
        #20 x = 3;
        #20 y = 1;
        #20 y = 0;
        
        #40 ;
        
    end
    
    initial begin
        $monitor("t = %3d x = %2b,y = %2b,z = %d \n",$time,x,y,z,);
    end
    
endmodule

Please note that the comments at the beginning were totaly removed!

Format result adding braces to stimulus:

`timescale 1ns / 1ps
module stimulus();
    // Inputs
    reg[1:0] x;
    reg[1:0] y;
    // Outputs
    wire z;
    // Instantiate the Unit Under Test (UUT)
    comparator2bit uut (
    .x(x),
    .y(y),
    .z(z)
    );
    
    initial begin
        $dumpfile("test.vcd");
        $dumpvars(0,stimulus);
        // Initialize Inputs
        x     = 0;
        y     = 0;
        #20 x = 1;
        #20 y = 1;
        #20 y = 3;
        #20 x = 3;
        #20 y = 1;
        #20 y = 0;
        
        #40 ;
        
    end
    
    initial begin
        $monitor("t = %3d x = %2b,y = %2b,z = %d \n",$time,x,y,z,);
    end
    
endmodule
