I want to copy the text in the subtree, but not the headline. Right now I
use the following hack:

  (org-narrow-to-subtree)
  (beginning-of-buffer)
  (next-line 1)
  (setq minPoint (point))
  (copy-region-as-kill minPoint (point-max))
  (widen)

However, org-copy-subtree would do exactly what I need, IF it did not copy
the headline. Then I could cut out four lines of the above code.
