Thanks for the examples. Anything goes, of course, but I'm hoping for a
tighter integration. Maybe a :prompt param to sh source blocks, which
sets the prompt in a session, and which also manipulates
`comint-prompt-regexp' or `shell-prompt-pattern' local in the session buffer.

Or a mechanism like in Tramp, where the shell prompt is set to a random
string not expected in the shell (see `tramp-end-of-output'), and
`comint-prompt-regexp' or `shell-prompt-pattern' are adapted
automatically local in the session buffer.
