Haha, in fact, you hit the nail right on the head (without realizing
it). :-)

It turns out to be entirely my fault after all: I have a wrapper shell
script that forwards to a local copy of lilypond (because I'm using a
local copy of guile-1.8 that I didn't want to conflict with the distro's
version), but I used the wrong forwarding for arguments:

        export LD_LIBRARY_PATH=/usr/src/guile-1.8/lib
        /usr/src/lilypond/bin/lilypond "$*"

where in the second line, I should have written "$@" instead.  This bug
went unnoticed because I usually only invoke lilypond with the single
.ly file as argument. But now when I need to pass additional arguments
to it, the "$*" smushes all the arguments into one where lilypond
expected multiple arguments, thus generating the observed mysterious
error message.

Changing it to "$@" fixed the problem.  Thanks a bunch, and sorry for
wasting everyone's time with something that isn't lilypond's fault at
all.
