Bug in "SustainPedal" ?

[Gilles]

Hi.

I use version 2.2.6.

I need the "sustain pedal" annotation, not on a piano double staff, but 
for a single staff (vibraphone).

As I indicated in a previous mail, the default position of the annotation
makes it clash with other symbols (dynamics, triolets).  As suggested, I 
tried the following:

  \override SustainPedal #'extra-offset = #'(-1 . -2)

To no avail: the sustain line doesn't move, whatever the numbers.

Also, when there are sustain markings on the score, the short
instrument name ("Staff.instr") is not centered correctly: instead
of being at mid-height of the staff, it seems to be centered with
respect to the total height between the sustain line and the top
line of the staff.


Best regards,
Gilles
