"git pull --rebase" is a close friend of mine ;-)

There is one problem with people relying on binaries instead of
building and improving lilypond itself: Almost nobody seems to be able to
bisect a problem. It's e.g. amazing to see how long it takes to track down
the speed problem on Mac OS systems.

I have to agree, although I still really do not like scheme. But solving the
the problem of optinal vertical alignment of lyric hyphens would require
to delay generation of the lyric hyphen stencils and to  hook into lilyponds
internals at a time when all lyric spanners of a system are known. I cannot
see where this could be done with reasonable effort. Any idea?
