Re-building Appendix A of notation.pdf

[Lukas-Fabian Moser]

Hi,

I'm probably missing something very obvious:

After changing a docstring in ly/music-functions-init.ly, what steps are 
necessary to re-build notation.pdf in order to check the result in "A.19 
Available music functions"? If I only delete notation.pdf and re-build 
it using

make -C Documentation out=www out-www/en/notation.pdf

I get the old docstring.

PS. Speaking of that appendix: I don't know much about typography, but 
the kerning of "Av" in

doesn't seem right to me. Is that as it should be? (The image is from 
the pdf in the official 2.22/2.23 build.)
