parser reads ties(slurs) incorrectly about abc4j HOT 2 CLOSED

Hi, your ABC is bogus.
- is a tie between 2 notes, to play note 1&2 as a single note of length = 
1.length + 2.length

() denotes a slur, which means to play legato

Try with
(B/2c/2)|(de) d(BA) B|...

You're right. My mistake, I understand the difference now. FWIW, I found this 
ABC on abcnotation.com, and poking around some more in their collection it 
seems like this tie-slur confusion is pretty common. So I don't know, having 
the parser interpret a "tie" between unequal notes as a slur might be worth 
doing, given the abc data that's in circulation, even though it's wrong.
