Patch to fix failure of lilypond-book in CVS

[Bernard Hurley]

Hi,

Current CVS version of lilypond-book fails when processing lytex files
with the error:

  File "/home/invisible/bin/lilypond-book", line 1686, in ?
    main ()
  File "/home/invisible/bin/lilypond-book", line 1652, in main
    chunks = do_file (file)
  File "/home/invisible/bin/lilypond-book", line 1532, in do_file
    if (c.is_plain () and
  File "/home/invisible/bin/lilypond-book", line 725, in is_plain
    return true
NameError: global name 'true' is not defined

The attached patch substitues 1 for 'true' it also substitutes 0 for
'false' which is likewise undefined
