Bug in rectify3Collinear calibration.cpp ? (Bug #1747)

In the function definition

 1float cv::rectify3Collinear( InputArray _cameraMatrix1, InputArray _distCoeffs1,
 2                   InputArray _cameraMatrix2, InputArray _distCoeffs2,
 3                   InputArray _cameraMatrix3, InputArray _distCoeffs3,
 4                   InputArrayOfArrays _imgpt1,
 5                   InputArrayOfArrays _imgpt3,
 6                   Size imageSize, InputArray _Rmat12, InputArray _Tmat12,
 7                   InputArray _Rmat13, InputArray _Tmat13,
 8                   OutputArray _Rmat1, OutputArray _Rmat2, OutputArray _Rmat3,
 9                   OutputArray _Pmat1, OutputArray _Pmat2, OutputArray _Pmat3,
10                   OutputArray _Qmat,
11                   double alpha, Size /*newImgSize*/,
12                   Rect* roi1, Rect* roi2, int flags )

the argument after alpha is not given a name. Probably the comment should be removed and the variable newImgSize used accordingly instead of imageSize in the calls:

2                   imageSize, _Rmat12, _Tmat12, _Rmat1, _Rmat2, _Pmat1, _Pmat2, _Qmat,
3                   flags, alpha, imageSize, roi1, roi2 );

6                   imageSize, _Rmat12, _Tmat12, _Rmat1, _Rmat2, _Pmat1, _Pmat2, _Qmat,
7                   flags, alpha, newImgSize, roi1, roi2 );
