-# By default this file 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 having #!/bin/bash -l.  I want something similar for ssh
-# commands. when a local script runs an ssh command, this file should not be
-# sourced by default, but we should be able to override that.
-#
-# So here we test for conditions of a script under ssh and return if so.
-# And we don't keep the rest of the code in this file, because even
-# though we return, we already parsed the whole code, and as I develop
-# the code, the parsing can have errors, which can screw up cronjobs
-# etc.
-#
-# To test for an overriding condition, we have a few options. one is to
-# use an environment variable.  env variables sent across ssh are
-# strictly limited. ssh -t which sets $SSH_TTY, but within a script that
-# won't work because tty allocation will fail. However, I do use -t for
-# strange hosts, so we consider it an indicator. 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. we could transfer a file
-# which we could test for, but I can't think of a way to make that
-# inherently limited to a single ssh command.  I choose to set SendEnv
-# and AcceptEnv ssh config vars to allow the environment variable
-# BASH_LOGIN_SHELL to propagate across ssh. This also requires that we
-# wrap ssh in interactive shells, because, once we export the var, it
-# will go into scripts, and we want it to be nondefault there.
-#
-# -c is set whenever a command is passed to ssh
-# -i is set whenever a command is not passed
+# see comments in brc2 sl() function for background.
