I read "CG Section 9. Regression tests" but I can't figure this out: where  
do you get this diff from?

The "Renaming input to" message is output by lilypond itself. I think that  
the other messages come from lilypond as well. Lilypond is now given a  
filename relative to the current directory, and that's what it prints out.  
I don't immediately see how to force either lilypond or lilypond-book to  
print filenames relative to the top source directory, as that is completely  
dependent on the particular layout of the lilypond source tree. But I guess  
with some hack it could be done.

So given that what you suggest, to output a path relative to the top source  
directory, would need some sort of hack, which of these second choice  
options is better:

1) I can probably figure out how to make lilypond print absolute paths for  
all filenames, to avoid these changes in regtest output.

2) Or we accept that lilypond outputs only the filename relative to the  
current directory, and look up the current directory from make's output.  
The script that makes the regtest diff could be modified to hide the  
renaming. There seems to be something along those lines already in  
scripts/build/output-distance.py: in class LogFileCompareLink the lines  
containing "\nProcessing `[^\n]+'\n" are removed.

By the way the build system outputs this already:

make[2]: Entering directory  
`/home/jrioux/git/lilypond-git/build2/input/regression'
make[3]: Entering directory  
`/home/jrioux/git/lilypond-git/build2/input/regression/midi'
make[3]: Leaving directory  
`/home/jrioux/git/lilypond-git/build2/input/regression
make[2]: Leaving directory  
`/home/jrioux/git/lilypond-git/build2/input/regression'
make[1]: Leaving directory `/home/jrioux/git/lilypond-git/build2/input'

etc.
