Interesting glitch when using tags ...

[Wol's lists]

I suspect the cause is that I'm mixing slurs and ties, but I'm getting 
the following error ...

voiceTrombone.ily:30:59: warning: unterminated tie
    \repeat percent 4 { f,8[ r f] f[ r f] } | f4.
                                                  ~ f4 r8 | a8-> r4 
a8-> r4 | a2. | bf2.(

but as you can see, I'm tying two f's together ... the crucial point is 
it does print correctly (well, it should be an inverted tie, but at 
least it prints a tie).

The context is:

    <<
        \tag #'TromI {
            \repeat percent 4 { bf8[ r bf] bf[ r bf] } | c4( d8 c4) r8 
| c8-> r4 c8-> r4 | c2. | c2. ~
        }
        \tag #'TromII {
            \repeat percent 4 { f,8[ r f] f[ r f] } | f4. ~ f4 r8 | 
a8-> r4 a8-> r4 | a2. | bf2.(
        }
    >>

you'll see that TromII has the tie, and TromI has a slur. BUT. If I 
change the tie to a slur, the error message disappears, but so does the 
slur joining the f's if I'm printing both parts ...

Interestingly, the eagle-eyed will notice that the last note of each 
part also ends with a tie in one part and a slur in the other, but this 
prints fine and doesn't generate an error ... odd ...

Cheers,
Wol
