The typo on this line guarantees that nobody will retain the current
location and will be migrated forcibly to the new xdg place ;-)

I somehow feel that the order of precedence should be the other way
around, though.  

If somebody really wants to use the xdg location and has a socket
already there, using that existing socket would be the right thing
to do.  However, when neither ~/.git-credential-cache/socket nor
~/.cache/git/socket exists, why should we prefer the latter over the
former?
