# When built with SSH_SOURCE_BASHRC, bash will source ~/.bashrc when
# it's non-interactively from sshd.  This allows the user to set
# environment variables prior to running the command (e.g. PATH).  The
# /bin/bash that ships with macOS defines this, and without it, some
# things (e.g. git+ssh) will break if the user sets their default shell to
# Homebrew's bash instead of /bin/bash.
