[BUG] Unable to parse (some) ModelSim lint messages

[Nativu5]

Describe the bug When I was trying to use modelsim to lint a file, the extension gave wrong parse result:

Environment:

• OS: Windows_NT x64 10.0.19043
• VS Code version: 1.61.2 (system setup)
• Extension version: v1.5.0
• lint: ModelSim Starter Edition 2020.1

Steps to reproduce Use ModelSim to lint the code below:

`timescale 1 ns /1 ns

`define AandBH  10'b0100000000
`define AorBH   10'b0010000000

module ArithmeticUnit (
	A, B, 
	B15to0, AandB, AorB, notB, shlB, shrB, AaddB, AsubB, AmulB, AcmpB,  
	aluout, cin,  cout, zout);

	input [15:0] A, B;
	input B15to0, AandB, AorB, notB, shlB, shrB, AaddB, AsubB, AmulB, AcmpB;
	input cin;
	output [15:0] aluout;
	output cout,zout;
	reg [15:0] aluout;
	reg  cout,zout;

	always @(
		 A or B or B15to0 or AandB or AorB or notB or shlB or shrB or AaddB or AsubB  or AmulB  or AcmpB or cin
	)
	begin
		cout = 0; aluout = 0;zout=0;
		case ({B15to0, AandB, AorB, notB, shlB, shrB, AaddB, AsubB, AmulB, AcmpB})
			`AorBH:  //add your code
			`AandBH: //add your code
			default: aluout = 0;
		endcase
		if (aluout == 0) zout = 1'b1;
    end
endmodule

Log

[Info] modelsim lint requested
[Info] 4 errors/warnings returned

Expected behavior L25 and L26 should be underlined according to messages from ModelSim.

Actual behavior

Additional context Other files' lint result can be parsed well. I have tried to move this file to another directory but the problem remained.
