# This file is meant to be executed directly. If it's available on the PATH,
# it can also be used as a subcommand of git, which then forwards all arguments
# on to forgit. So, all of these commands will work as expected:
#
# `git forgit log`
# `git forgit checkout_file`
# `git forgit checkout_file README.md`
#
# This gives users the choice to set aliases inside of their git config instead
# of their shell config if they prefer.
# Set shell for fzf preview commands
# Disable shellcheck for "which", because it suggests "command -v xxx" instead,
# which is not a working replacement.
# See https://github.com/koalaman/shellcheck/issues/1162
