_cd(): sigh, completion on dirs and subdirs of entries in $CDPATH was broken

yet again, this time due to the space having been removed from local $IFS.
  This is fixed now, but there's still a bug remaining, namely that completion
  does not work correctly if dirs or subdirs of entries in $CDPATH contain
  embedded spaces
_longopt(): install completion for {mk,rm}dir as -o filenames, not dirnames
