lilypond-book: \usepackage not always generated Ver 2.7.20 /ChangeLog/1.4307/

[Bernard Hurley]

lilypond -book still does not always generate \usepackage. (The code
seems to have changed but the issue remains)

After runing:

lilypond-book -V --psfonts test-X.lytex

on either tof the following files does not result in \usepackage
{graphics} being inserted into the generated .tex file.

----------- test-1.lytex --------
%% comment
\documentclass[english]{article}
\begin{document}
\end{document}
---------------------------------

----------- test-2.lytex --------
\documentclass[english]{article}
%% comment
\begin{document}
\end{document}
---------------------------------
