When I use "org-edit-special" in an org babel block, I get this traceback:

Debugger entered--Lisp error: (wrong-type-argument listp t)
  delete((org-filtered) t)
  remove((org-filtered) t)
  org-move-to-column(5)
  org-edit-src-code()
  org-edit-special(nil)
  funcall-interactively(org-edit-special nil)
  call-interactively(org-edit-special record nil)
  command-execute(org-edit-special record)
  execute-extended-command(nil "org-edit-special" "org-edit-sp")
  funcall-interactively(execute-extended-command nil "org-edit-special"
"org-edit-sp")
  call-interactively(execute-extended-command nil nil)
  command-execute(execute-extended-command)


The reason for this seems to be a rewrite of the c function "delete", that
does not accept "t" instead of a list anymore. I guess it was done for a
reason.
I think "org-move-to-column" causes the problem as it is called in org-src
buffers. I tried "org-move-to-column" in an org buffer and it seems to work.



My solution would be to use "move-to-column" instead:
