Another question related to using babel, shell commands, in a session: When I try to export a .org file with "begin_src sh :session *shell* :exports code" blocks, I'm prompted whether I want to evaluate the code. However, I thought ":exports code" would avoid evaluation on export (and that :session is only about evaluation).
Any help appreciated.

That is, I want readers to read along, and then execute the code as needed. Currently, it never returns (until C-g). It might be related to the issues discussed last November, http://lists.gnu.org/archive/html/emacs-orgmode/2009-11/msg01166.html I have the latest git version of org mode, and I think I've set comint-prompt-regexp correctly. So: I don't want to filter the output, I don't want to collect the results - just send the commands and go. Looking at ob-sh.el/org-babel-sh-evaluate, I can't figure out what the Right Thing to do is. Appended is a cheap hack that checks for "ignore" as a results string (e.g. #+begin_src sh :session *shell* :results ignore) and sends the lines one at a time to the inferior shell buffer. But I suspect there's a more straightforward way to do it. Thoughts?
