# ssh, copy my universal config over if needed.

# By default .bashrc is sourced for ALL ssh commands. This is wonky.
# Normally, this file is not sourced when a script is run, but we can
# override that by sourcing ~/.bashrc.  I want the same thing for ssh
# commands. when a local script runs an ssh command, bashrc should not be
# sourced, unless we use a modified command.
#
# So, in my bashrc, test for conditions of noninteractive ssh and return
# if so.  And we don't keep the rest of the code in .bashrc, because
# even though we return, we parse the whole file which can cause errors
# as we develop it.
#
# To test for an overriding condition: bash builtin vars and env show no
# difference in ssh vs local, except shell level which is not
# reliable. one option is to use an environment variable. env variables
# sent across ssh are strictly limited. We could override an obscure
# unused LC_var, like telephone, but I don't want to run into some edge
# case where that messes things up. I choose to set SendEnv and
# AcceptEnv ssh config vars to allow the environment variable BRC to
# propagate across ssh, and for hosts I don't control, I start an inner
# shell with it set, which doubles up as a way to have a nondefault
# bashrc.
