Sigh.  LilyPond does not access a manual in any manner.  It is a
program.  How about saying just what link you used?

Now the line "lilypond" is not likely to make LilyPond happy.  On
2.19.65, this is the only line LilyPond complains about and compiles
fine otherwise.

Removing it works on both 2.19 and 2.18.  The interesting question is
just what happens with 2.18 here?

It turns out that

lilypond cuatroTuning = ...

sets the value of the variable "lilypond" without voicing any complaint
about cuatroTuning being undefined.  Looking at the grammar of 2.18, we
see that this is equivalent to lilypond.cuatroTuning = ... and looking
at the called set_identifier routine, we find that for a previously
undefined variable lilypond, setting lilypond.cuatroTuning sets lilypond
instead.  Another problem later cured, but setting lilypond.cuatroTuning
would not actually have helped.

So a curious syntax (which was impossible in 2.16 and has been
invalidated in 2.19 since it could lead to problems like the one you
experienced) absorbed the spurious "lilypond" you put in your file,
leading to a lot of followup errors.
