I ran into an issue with bash blocks that use a session where
'org_babel_sh_prompt> ' is strewn throughout the output. For large
blocks the intended output can be completely buried. Here is an example.
#+begin_src bash :session test :results output
echo "hello"
#+end_src
#+RESULTS:
: org_babel_sh_prompt> org_babel_sh_prompt> org_babel_sh_prompt> org_babel_sh_prompt> hello
This is caused by a leading carat in the `comint-prompt-regexp` regex in `org-babel-sh-initiate-session` in `ob-shell.el`, and the fix is incredibly simple.
Here is the diff that I've generated.

This is my first OSS contribution, I initially reported this to the main emacs bug report email using their guidelines. If I need to alter this in any way, let me know and I am willing to make changes.
