Too bad.  I'm glad I don't really need one :)

My MIDI files sound much better now that you told me that!  Thank
you!

After trying almost all permutations of \tempo, s1*0 and markup, I came
to this working solution:

aTempo = { \tempo 4=58 s1*0 -"a tempo" }
rit = { \tempo 4=42 s1*0 -"rit." }
moltoRit = { \tempo 4=38 s1*0 -" molto rit." }
...
% In the melody part
\override TextScript #'direction = #UP
\override TextScript #'font-shape = #'italic
\set Score.tempoHideNote = ##t

By the way, I'm surprised we have dynamicsUp and even dotsUp but not
textScriptUp.
