  Dear Org-Mode Users

* body
  Lately, I have been composing formal letters using KOMA script's
  scrlttr2. I find it convenient to have them composed auto-magically
  from within org-mode.
  
  I am enclosing the initial set of changes needed to compose some
  simple letters as this one.
  
  The only change that is too 'intrusive' seems to be an extra newline
  which gets added immediately after the emission of labels. These
  extra newlines trigger syntax errors in the closing{} and encl{}
  directives.
  
  I think rest of the changes could be squeeed in through existing
  hooks.

#+BEGIN_EXAMPLE
-         (insert (mapconcat (lambda (l) (format "\\label{%s}" l))
-                            label-list "\n") "\n"))
+           (insert (mapconcat (lambda (l) (format "\\label{%s}" l))
+                              label-list "\n")))
#+END_EXAMPLE 
  
  If there is some general interest, I could work on making a formal
  patch available.
