Bug: :session doesn't honor :verbatim [8.2.10 (release_8.2.10 @ /usr/local/share/emacs/26.0.50/lisp/org/)]

[Michael Albinus <michael.albinus@gmx.de>]

Hi,

when I eval the following source block, everything is fine:

#+BEGIN_SRC sh :results verbatim
df -h /
#+END_SRC

#+RESULTS:
: Filesystem      Size  Used Avail Use% Mounted on
: /dev/sda6       137G   55G   76G  43% /

However, using a :session shortens the output unexpectedly:

#+BEGIN_SRC sh :results verbatim :session *session*
df -h /
#+END_SRC

#+RESULTS:
: 
: Mounted on
: /

I suppose it is due to the "%" character in the output, because the
following works fine:

#+BEGIN_SRC sh :results verbatim :session *session*
df --output=source,size,used,avail,target -h /
#+END_SRC

#+RESULTS:
: Filesystem      Size  Used Avail Mounted on
: /dev/sda6       137G   55G   76G /
