This change allows git-svn to support setting subversion properties. Very useful for manually setting properties when committing to a subversion repo that *requires* properties to be set without requiring moving your changeset to separate subversion checkout in order to set props. This change is initially from David Fraser Appearing here: http://marc.info/?l=git&m=125259772625008&w=2 They are now forward ported to most recent git along with fixes to deal with files in subdirectories. Style and functional changes from Eric Wong have been taken in their entirety from: http://mid.gmane.org/20141201094911.GA13931@xxxxxxxxxxxxx There is a nit that I want to point out. The code does not support adding props unless there are also content changes to the files as well. You can see this in the testcase.
