When noweb reference in org-mode 's source code block is expanded, ever the content of the reference consists of only one line, it will expand the reference with an surplus line. This is an example:
The source block is :
#+srcname: test
#+begin_src sh
hello
#+end_src
#+begin_src sh :tangle ~/tmp/1.sh
echo "<<test>>, world!"
#+end_src
and the block's expand result is:
echo "hello
echo ", world!"
How can I modify OR setup, so that I can get the expand result like this:
echo "hello, world!"
Answer: see the comment.
