\transposition normalized

[Jay Anderson]

If I have a section like:

\relative c'
{
  \time 4/4
  \transposition f
  c e g c |
  \transposition ees
  c, e g c |
  \transposition d
  c, e g c |
}

Is there an easy way to change it all to the same key for printing?

Something like '\normalizeTransposition f \music' would be equivalent to:

\relative c'
{
  \time 4/4
  \transposition f
  c e g c |
  bes, d f bes |
  a, cis e a |
}

Thanks.
