That said, your patch pushes it forward even if one could raise some cosmet= ic conerners. Preferably you would mail git format-patch output to me so that i can git a= m, otherwise I'm going to write my own commit message and set you as the autho= r. --=20 You are receiving this mail because: You are the assignee for the bug.=
