TypeScript code being linted

import Backbone = require('backbone');
import Marionette = require('backbone.marionette');
import { LoggingService, LogLevel } from '../util/logging/LoggingService';

export class AitrItemView<T extends Backbone.Model> extends Marionette.ItemView<T> {
    public handleError(error: any, command: string) {
        error = error || 'Error processing command';
        let message = error.message || error.Message || error;
        if (command) {
            message = command + ' failed.\n    ' + message;
        }

        LoggingService.log(message, LogLevel.error, error);
    }
}

with tslint.json configuration:

{
    "defaultSeverity": "error",
    "extends": [
        "tslint:latest"
    ],
    "jsRules": {},
    "rules": {

    },

}

Actual behavior

running npm run tslint runs tslint --project ./tslint.json which produces the following errors:
ERROR: app/aitr/Aitr.ItemView.ts[2, 1]: statements are not aligned
ERROR: app/aitr/Aitr.ItemView.ts[3, 1]: statements are not aligned
ERROR: app/aitr/Aitr.ItemView.ts[5, 1]: statements are not aligned

If run with --fix option, the code is modified to insert a single space as the first character in front of all three lines, as below. This is incorrect, as the statements are already aligned.

import Backbone = require('backbone');
 import Marionette = require('backbone.marionette');
 import { LoggingService, LogLevel } from '../util/logging/LoggingService';

 export class AitrItemView<T extends Backbone.Model> extends Marionette.ItemView<T> {
    public handleError(error: any, command: string) {
        error = error || 'Error processing command';
        let message = error.message || error.Message || error;
        if (command) {
            message = command + ' failed.\n    ' + message;
        }

        LoggingService.log(message, LogLevel.error, error);
    }
}

This error is repeated for MANY other files, but not for all files in my project.

Expected behavior

No errors generated from above code.

This happens for files encoded in UTF8 with BOM, when the first statement is on the first line.
I recently fixed the same problem for jsdoc-format. I'm already working on a fix.

Thanks for getting this done quickly.
