Issue 457: general problem with \override and \once \override
http://code.google.com/p/lilypond/issues/detail?id=457

New issue report by lemzwerg:
\version "2.11.31"

\header { texidoc = "
@code{\once \override} must restore the value previously
set with @code{\override}.

Here's a counterexample.  I consider this a serious
bug in the @code{\override} mechanism since it prevents
the user from setting up new default values.
" }

\relative c' {
  \override TupletBracket #'padding = #10

  \times 2/3 { r8 e[ d] }
  \once \override TupletBracket #'padding = #5
  \times 2/3 { r8 e[ d] }
  \times 2/3 { r8 e[ d] }
}

\paper {
  ragged-right = ##t
}
