To use this:

#+begin_src sh :term t
ls -l
echo "Hello world"

Probably good to replace the "/bin/zsh" call with
(or explicit-shell-file-name (getenv "ESHELL") (getenv "SHELL")

So the original context of this was that zeltak wanted a way to run sh
babel blocks in a separate term so that he could interact with the
results of the process instead of having the output go into a results
block. I'm not sure if there's already a proper way to do this (didn't
seem like it from org-babel-execute:sh), so I added a custom :term
parameter and advised the execution of org-babel-execute.sh. Seems to

Of course, proper implementation would get rid of the advice, and also
maybe use :results term or something like that. Anyway, before we dig
into implementation details and documentation updates: Is interacting
with babel output something that might be interesting to include? If so,
how should it behave?
