I am branching off this bug into a new thread.

Reproducer:

#+begin_src dash
  echo This must be empty in dash: "$RANDOM"
#+end_src

#+RESULTS:
: This must be empty in dash:



#+begin_src dash :cmdline 1 2 3
  echo This must be empty in dash: "$RANDOM"
#+end_src

#+RESULTS:
: This must be empty in dash: 25561

The second code block uses shell as evidenced by $RANDOM variable being
initialized. This only happens when :cmdline header argument is
provided.
