The reason that I chose '(&' for start and '&)' for end is that they
are not ambiguous - it makes no sense to see a single '&' immediately
at the beginning or end of a slur. It does make sense to see a single
'&' just before a slur that that is why I did not pick '&(' for the
opening start token.
Having a single '&' mean "reset to last '(&' if given or to last
barline if not" would make sense to me.
