If we add core.addremove=true the same applies to it - we cannot remove
it later, the only we can do is to disable it by default in future
versions after testing (core.addremove=true or core.mode=next).

BTW, I'm still using pre-1.6 git-foo, I have /usr/libexec/git-core
in my PATH. So I would like to always have an option to disable some
new incompatible "improvements".
