From: David Turner <dturner@xxxxxxxxxxx>
Make it possible to change the case of a filename on a
case-insensitive filesystem using git mv. Change git mv to allow
moves where the destination file exists if either the destination file
has the same inode as the source file (for Mac) or the same name
ignoring case (for Win).
