sure, not working on $ sign too

code:

    public checkDocument(document: vscode.TextDocument = vscode.window.activeTextEditor.document) {
        shelljs.exec(`proselint --json "${document.fileName}"`, (code, output, error) => {
//                                     ^
//                               problem here!
            this.proseLintResult(document, code, output, error);
        });
    }

My suggestion: Use spawn instead of exec, and get free from escape hell!

exec(`proselint --json "${shellEscape(document.fileName)}"`) ...

// =============================================================

spawn(exePath, ["--json", "--", document.fileName]) ...
