If you give a prefix arg to erlang-shell, it reads arguments from the
minibuffer. The tricky part is that you also have to set the TERM env var.
So, if you type

C-u M-x erlang-shell

you'll be prompted with "Erlang command: " to enter the erlang shell
command. At the prompt enter something like the following:

erl -sname bilbo -remsh gandalf@REDACTED -env TERM vt100

The "-env TERM vt100" part is very important, since if you leave it off,
the new node will start just fine but will silently fail to connect to the
other node.
