[O] How to treat string results of src-block calls like text in export?

[Thorsten Jolitz]

Hi List, 

with this org file

,----
| #+name: project-name
| #+header: :exports none
| #+begin_src emacs-lisp
|   (mapconcat
|    'capitalize
|    (split-string
|     (file-name-nondirectory
|      (directory-file-name
|       (file-name-directory
|        (buffer-file-name (current-buffer)))))
|     "-" 'OMIT-NULLS)
|    " ")
| #+end_src
| 
| * call_project-name()
| some text
| 
| * Sourcedir
| more text
`----

I get this when exporting to ascii (excerpt):

,----
| Table of Contents
| _________________
| 
| 1 `Testdir'
| 2 Sourcedir
| 
| 
| 1 `Testdir'
| ===========
| 
|   some text
| 
| 
| 2 Sourcedir
| ===========
| 
|   more text
`----

and this when exporting to latex (excerpt):

,----
| \section{\texttt{Testdir}}
| \label{sec-1}
| some text
| 
| \section{Sourcedir}
| \label{sec-2}
| more text
`----

How do I achieve that the string returned by the src-block call is
treated just like normal text? 

I tried using (format ...) as well as several :results options, even
(intern ...), but to no avail.
