make-sequential-music expects a list?

[Pedro Kröger]

The manual says
(http://lilypond.org/doc/v2.5/Documentation/user/out-www/lilypond/Input-variables-and-Scheme.html#Input-variables-and-Scheme)
that this should work:

#(ly:export (make-sequential-music newLa))

but I have to do this instead:

#(ly:export (make-sequential-music (list newLa)))

is the manual just wrong or am I missing something?
