Example, please.  I *really* don't know how to create `8___|' as a
markup text.

In general I think it's problematic to have special cases for spanners
which can't be handled by default.  What about this: In case a single
note gets both a `\spanrequest \start ...' and a `\spanrequest \stop
...', lilypond automatically creates a dummy grob positioned at the
same place as the note (and having the same properties) which serves
as the second item for the spanner.  There are a *lot* of useful
applications for this:

  . Ottava lines as described above

  . Pedal markers `Ped. *' for a single note.

  . l.v. ties, i.e. short ties which start at a given note but don't
    have an end note -- have a look into Debussy's piano preludes for
    examples.

and so on.
