Hi, Pete,

the semantics for repeats with upbeats are explained in

http://lilypond.org/doc/v2.13/Documentation/notation/Long-repeats#Normal-repeats

In essence, you need the following layout (note the positions and 
durations of the \partials):

TrumpetUpper = {
  \key f \major
  \time 2/2
  \partial 4
  \repeat volta 2 { c4 | c c c c | c r r }

  \repeat volta 2  { a | a a a a | a a a a }
  \alternative {
    { | g g g g | \partial 2. g g g }
    { | f f f f | f f f }
  }
  e | e e e
}

\score {
  \new Staff \relative c'' { \TrumpetUpper }
}


Cheers,
Alexander
