The recently introduced conditional inclusion of configuration did
not work well when early-config mechanism was involved.

* nd/conditional-config-in-early-config:
config: correct file reading order in read_early_config()
config: handle conditional include when $GIT_DIR is not set up
config: prepare to pass more info in git_config_with_options()
