Inside `org-babel-comint-with-output', BODY may send multiple commands
to the shell; one by one. Their output will also arrive one by one,
separated by PROMPT. The return value is a list of these outputs.
If we were to concatenate this list, the information about which part of
the output belongs to which submitted command would be lost.
The docstring may indeed be improved.
