Well, actually I searched for a _function_ returning the unbroken
_item_, because I was under the impression ly:grob-original was fpr
spanners only.
Thus I didn't try it out, my bad.

After a night full sleep, I reseached ly:grob-original in our code base.

I found only one instance where ly:grob-original is used for grobs
which may not be spanners: `offsetter' in music-functions.scm.
Though IR says:
Function: ly:grob-original grob
  Return the unbroken original grob of grob.
Coming from
Return the unbroken original grob of @var{grob}.
in grob-scheme.cc

I think it would be more clear to do
Return the unbroken original grob of @var{grob}, @var{grob} may be an
item or spanner.

If you agree I'd put up a patch.
