I removed it. No change.

A version of somewhere last week.

Just did:

--8<---------------cut here---------------start------------->8---
git pull
make clean
make
--8<---------------cut here---------------end--------------->8---

No change (after Emacs restart).

Yep.

Though, there is one blank line in front:

--8<---------------cut here---------------start------------->8---

[sva@mundaneum] ~>
                  ^ cursor blinking here
--8<---------------cut here---------------end--------------->8---

I don't know if that's worth mentionning...

Tried as well this change:

--8<---------------cut here---------------start------------->8---
;; for single shell commands
(setq shell-file-name "zsh")
--8<---------------cut here---------------end--------------->8---

Same problem (after Emacs restart).

> Sorry not a big help at least a pointer that it should work...

Thanks anyway. It's helpful to know someone gets it working the same way (at
least, from a first observation).

Just note that the following works well:

--8<---------------cut here---------------start------------->8---
#+begin_src sh
cd ~/Personal
ls *.org
#+end_src

#+results:
| "Bookmarks.org"                       |
| "Home.org"                            |
| "refile.org"                          |
| "Scorpios.org"                        |
| "Succession.org"                      |
| "Tickler.org"                         |
| "Using-startx-for-Remote-Display.org" |
| "Voice-over-IP.org"                   |
--8<---------------cut here---------------end--------------->8---

It stops working only when I add `:session "whatever"' after the `sh'
specification.

That's the only difference between when it works and when it doesn't.

Maybe this can help?

Best regards,
  Seb
