lilypond-book windows 5

[Graham Percival]

I believe this will at least produce the default line-widths
out-of-the-box for any texinfo or latex file, regardless of
whether texi2pdf is in the path or not.  Please test.

I am hopeful (though I am not optimistic) that it will work with
texi2pdf.exe rather than texi2dvi.exe.  However, I consider that a
separate issue: if this version can reliably give default
line-widths, I want to get it merged and 2.15.25 out the door.
