tie-configuration question

[Henrik Frisk]

In a post a few weeks back I asked about the tie-configuration in
mulitiple voices. Nobody responded, so either it ws a really dumb
question - in which case I don't mind being told - or nobody understood
what I meant... In either case, here's a snippet that doesn't change the
tie behaviour. I've tried a number of different ways of coding the same
music, but as long as there is more than one voice, I can't get
tie-configuration to make a difference.

I think the recent discussions on LilyPond's new tie
behaviour has shown one thing: To a large degree it is up to musical style and
personal preference - which makes the tie-configuration command so
important (to me anyways).
