It's not that tricky. At first sight, you may even think that there is
no need for
a music function at all, but as you probably have found out yourself, an
identifier like
myGrace = { \once \override Slur #'transparent = ##t \appoggiatura }
does not work. The reason is that \appoggiatura itself is a music function,
that takes one argument, namely the grace note(s). So, what you need is a
music function that takes a music expression as an argument:
\version "2.10.0"
wideGrace = #(define-music-function (parser location grace) (ly:music?)
#{
\once \override Slur #'transparent = ##t \appoggiatura $grace
#})
\relative c'{
c \grace d8 e4 \wideGrace f8 g4 c
}
\layout{ragged-right=##t }

Thanks, Graham. I had followed links as far as 5.6, which didn't help. Ch.
12, "Interfaces for programmers", is serious stuff, as the title says. I
might work on it when I have more time for study.
