git-bug does not currently read bridge credentials from anything except the user configuration file, e.g. ${HOME}/.gitconfig. It would be awesome if the full configuration chain could be supported, in order of precedence:

• Local configuration -- ${REPO_ROOT}/.git/config
• User configuration -- ${HOME}/.gitconfig or ${XDG_CONFIG_HOME}/git/config
• System configuration -- /etc/gitconfig

Additionally, following include directives would be useful -- the main application for which is likely keeping the authentication configuration out of the default user-scoped conffile which is stored in a repository for public sharing.
