Comment (by Peter.Danecek@…):

 On MacPorts Development I got feedback that the patch was could not be
 applied.

 I checked this and had no problem. However, apart from unified format, I
 am not aware of any requirements on patch files for submission here. I
 have looked a bit around but have not found any documentation on this. So
 if these special requirements exist, please point me the right place to
 look at.

 Otherwise, just let me know what you would need. Thanks!
