Attempting to put my money where my mouth is: find attached a patch to
restore org-export-current-backend.  I think this is a TINYCHANGE
despite the large diff -- it's almost all whitespace, and the docstring
is restored verbatim from org-mode 7.9 (I haven't updated it for the
removal of the docbook backend, for example, primarily so that it has
minimal novel information in it).
