start and end points of ligatures

[Nancho Alvarez]

Hello!
I have seen a problem with ligatures, the horizontal bracket joining 
notes denoted with \[ and \].

The problem is that the start and end point of the bracket seems to be 
affected by the rythmic figures of other simultaneus voices.
In this small example, the first bracket has an incorrect end point (too 
far apart from the note). The second one is correct.

Thanks.
