#
# recursive-gitconfig: Alias git to use closest .gitconfig file found in parents directories.
#
# Quick example:
#
#     # Make dirs & .gitconfig files
#     mkdir -p /tmp/gitenvs/john && mkdir /tmp/gitenvs/jack
#     touch /tmp/gitenvs/john/.gitconfig && touch /tmp/gitenvs/jack/.gitconfig
#
#     # Set values to config files
#     git config -f /tmp/gitenvs/john/.gitconfig --add user.name 'John'
#     git config -f /tmp/gitenvs/john/.gitconfig --add user.email 'john@local'
#
#     git config -f /tmp/gitenvs/jack/.gitconfig --add user.name 'Jack'
#     git config -f /tmp/gitenvs/jack/.gitconfig --add user.email 'jack@local'
#
#     # Create git repositories under config files
#     mkdir /tmp/gitenvs/john/repo/ && git --git-dir /tmp/gitenvs/john/repo/.git init
#     mkdir /tmp/gitenvs/jack/repo/ && git --git-dir /tmp/gitenvs/jack/repo/.git init
#
#     # Commit & test behaviour
#     cd /tmp/gitenvs/john/repo && git commit --allow-empty --message "John's" && git log
#     cd /tmp/gitenvs/jack/repo && git commit --allow-empty --message "Jacks's" && git log
