David Aguilar d81345ce09 difftool: fix bug when printing usage ...

"git difftool -h" reports an error:

	fatal: BUG: setup_git_env called without repository

Defer repository setup so that the help option processing happens before
the repository is initialized.

Add tests to ensure that the basic usage works inside and outside of a
repository.
