lilypond-book 2.17.21 and spaces in file path

lilypond-book 2.17.21 can't determine the line width from .lytex files
if there is a space in the file path, while spaces only in the file name
don't cause any problem.


I tried to compile the following example with lilypond-book 2.16.2
and 2.17.21, saving the file as "~/test/test.lytex",
"~/test/te st.lytex" and "~/te st/test.lytex" (notice the spaces).

\documentclass{article}
\begin{document}
\begin{lilypond}
\repeat unfold 20 { c'1 }
\end{lilypond}
\end{document}

lilypond-book 2.16.2 compiles correctly in each case.
lilypond-book 2.17.21 compiles correctly in the first two cases,
while in the third case ("~/te st/test.lytex") it produces too wide
systems and gives the following output on terminal

$ lilypond-book --output=out --pdf test.lytex
lilypond-book (GNU LilyPond) 2.17.21

Running `pdflatex' on file `/var/folders/XN/XNp3zsn1G-WeL9c1ocHiuE+++TI/

I believe the problem is in file
"share/lilypond/current/python/book_latex.py".
Here is part of the diff between version 2.16.2 and 2.17.21:
I think the problem may be that the string that is added to $TEXINPUTS
at line 192 is not quoted.
(I didn't try to edit the "book_latex.py" and check if this is correct.)
