This is different from the question I asked, because I wanted to know  
what happens if quotes are passed on to 'lilypond', as in
  lilypond 'foo bar'
The reason is that bash may not pass on the quotes themselves, only  
the arguments (I don't remember this).

But if you have the binary, it should work.

In C code, one uses the function system(), which just passes on a  
string to a subshell.

If you know what names are used in Emacs Lisp, you can search for  
them in the lilypond-make script. Section 37.1 Functions that Create  
Subprocesses in the Lisp reference manual
  http://www.gnu.org/software/emacs/manual/elisp.html
gives names like start-process, call-process and call-process-region.
