Not true on my Windows machine. After every run of LP there is a
filename-lilypond-1-1.pdf with exactly the same size as the pstopdf
generated.
Ok, you're right - a normal LP run (PDF backend) cannot create
snippets, but the EPS-backend run does - *plus* it converts eps to pdf
by itself. I didn't know the latter; I guess it was introduced only
some versions before.
Try to compile the .tmp file with a normal LilyPond call, and you get
a page-size PDF. The intermediate .ps file is deleted by LilyPond
itself, but you can see it sometimes flash. LilyPond does the
conversion to PDF in a second step, AFAIK with its build-in GhostScript.
This is a normal LilyPond run (in German); it mentions the
intermediate .ps file and the conversion:
hraban$ lilypond test.ly
GNU LilyPond 2.12.2
»test.ly« wird verarbeitet

Interpretation der Musik...

This is the LilyPond run as executed by t-lilypond:
hraban$ lilypond -dbackend=eps -dno-gs-load-fonts -dinclude-eps-fonts -
ddelete-intermediate-files -o"test" test.ly
GNU LilyPond 2.12.2

file (string-append base "." ...)):

library.scm:149:21: No such file or directory
You see it creates from the one input file two EPS and PDF files each,
that seem exactly the same - I'll investigate and ask on the LilyPond
mailing list.
The error message isn't nice either, but it doesn't seem to hurt -
maybe it's about the useless files, since it mentions "delete-file".
