Hi Rainer,

I actually believe that the current behavior is the more "correct"
behavior, however I'm not sure if the default padding behavior is
technically specified when no ":padline" header argument is given.

The following combination of header arguments results in the desired
behavior.  Note that the shebang line isn't required, I was just using
it to easily view file contents and to see if an empty line was inserted
between shebang and contents.

#+begin_src R :tangle test.R :shebang #!/bin/cat :padline no
This is
a test
#+end_src
