1) "make distclean" does not remove symlinks in ./out/ , such as
./out/bin/* and ./out/share/locale/. As a result, trying to grep for
anything in the source tree produces a whole bunch of "No such file or
directory" messages. It's quite a minor thing, but still a bit
2) Could "make -C python" be added to the "make web" rules? I'm
thinking specifically about make LILYPOND_EXTERNAL_BINARY here... it
would be nice to advertise this possibility, and the "make -C python"
line seems unnecessary for the user to type manually.
