Comment #10 on issue 1821 by percival.music.ca: GUB argument list too long
http://code.google.com/p/lilypond/issues/detail?id=1821

I've added an --input-filename=  option to lys-to-tely.

However, the $(foreach ...) proposal for lysdoc.make still lists everything  
on the same command-line.  I'm also concerned about the dependencies for  
collated-files.list -- if we don't do this carefully, the build system  
won't regenerate collated-files.list if a new regtest is added.

I'd be happy if we simply regenerated this list every time.  IIRC that's  
not too hard to do in make, but I don't know how offhand.
