I was about to ask the same thing... I am able to create tighly clipped pdf 
files with these settings (which are awkward to type/copy manually into each 
snippet you want to create... Can't we define a global command that sets these 
as default values? Something like \setTrimmedOutput, which would set the 
margins to 0 and cause lilypond to produce a pdf file with no margins around 
the score without any need for strange command-line options...)

Unfortunately, the eps backend creates an error in the postprocess-output 
function:
/home/reinhold/lilypond/lilypond/out/share/lilypond/current/scm/backend-
library.scm:154:21: In procedure delete-file in expression (delete-file (string-
append base "." ...)):
/home/reinhold/lilypond/lilypond/out/share/lilypond/current/scm/backend-
library.scm:154:21: No such file or directory

The reason is that for the "pdf" output format, the completize-format returns 
"ps" rather than "eps" as intermediate formats, so lilypond tries to delete 
the intermediate file myfile.ps, which of course doens't exist. On the other 
hand, myfile.eps is not detected as intermediate file...

I don't see any easy solution, since the intermediate files are backend-
dependent and the completize-format function does not have any pointer to the 
backend...

Cheers,
Reinhold
