Fix issue 809.

Patch by: Marcus Comstedt <marcus@mc.pp.se>

* subversion/clients/cmdline/util.c
  (svn_cl__edit_externally): Avoid the need to put base_dir into the
  tmpfile filename by doing a cd there first.  Fixes issue #809.
  Fixed problem in cleanup code with using tmpfile_native, which may
  not have been initialized yet.
  Fixed one spelling error.
