Allow users to un-configure rename detection
I told people on the kernel mailing list to please use "-M" when sending me rename patches, so that I can see what they do while reading email rather than having to apply the patch and then look at the end result. I also told them that if they want to make it the default, they can just add [diff] renames to their ~/.gitconfig file. And while I was thinking about that, I wanted to also check whether you can then mark individual projects to _not_ have that default in the per-repository .git/config file. And you can't. Currently you cannot have a global "enable renames by default" and then a local ".. but not for _this_ project". Why? Because if somebody writes [diff] renames = no we simply ignore it, rather than resetting "diff_detect_rename_default" back to zero. Fixed thusly.
