[O] [Babel] Blank line preceeds tangled data

[Bernt Hansen]

Hi,

When I tangle some file such as

#+begin_src sh :tangle x.sh
  #!/bin/sh
  echo done
#+end_src

I get the following output which includes a blank line up front.

,----[ x.sh ]
| 
| #!/bin/sh
| echo done
`----

Doesn't this break the shebang line on unix?  I don't think the leading
blank line should be in the tangled output.

Regards,
Bernt
