Nothing from you yet... Did I miss anything? Is it related to the
discussion with Andrew on -bug?

Hm. Sent to your usual address and bug about 21 hours ago (according to gmail). But I don't see anything in the bug archive. Probably got rejected by the bug list because I did the unthinkable: attached two small pngs showing the problem. Here's a duplication of the original mail, you'll have to compile the examples other than the first:

Hi Valentin,

Could you please consider this one for the tracker?

=== BEGIN DESCRIPTION ===

In each of the snippets below, the third spanner displaces considerably too far to the left. In each case, the left edge of the spanner left-aligns with the dynamic or markup in the *remote* staff; edge such spanner should instead left-align with the left edge of its parent notehead only.

=== END DESCRIPTION ===

If possible, could we consider a somewhat higher priority ranking for this one? I think maybe there are three good reasons to do so:

a. the problem is very general -- different types of spanner (trill, text), different types of associated bound object (dynamics, text script) all show the problem;

b. there doesn't seem to be an easy workaround -- we'd have to know something like half the width of the associated bound object (in staff spaces) in order to be able to correct the problem with something like 'extra-offset;

c. one of the biggest chunks of new functionality in 2.11 is the new spanners package that Han-Wen and I worked on this time last year (that introduced bound-details, for example, to grant independent control of left and right spanner details), and this bug damages at least the left-hand part of that feature package.

Thanks!
