Thanks. you gave me enough hints to construct my preferred solution.

\version "2.17.97"

\addInstrumentDefinition #"Treble"
  #`((instrumentCueName . ,(make-bold-markup "treb.")))

\addInstrumentDefinition #"Tenor"
  #`((instrumentCueName . ,(make-bold-markup "ten.")))

\layout { \context { \CueVoice \remove "Instrument_switch_engraver" } }

{
  g'1
  \once \override InstrumentSwitch.font-size = #-4
  \new CueVoice {
    \instrumentSwitch "Treble"
    g'1
  }
  \instrumentSwitch "Tenor"
  g'1
}
