Missing links to interfaces?

[Mats Bengtsson]

Hi,

Related to Cameron's question on which objects can get an arrow by
setting the arrow property, I thought that it was just to look up which
interface contained the property -> line-spanner-interface, and then to
look up which grobs implement this interface and it turned out that
I only found Glissando and VoiceFollower. However, I know from the
Regressions Tests example that you can set the property for example also
on TextSpanner.

I'm not sure how to correct this. Is it just that the 
line-spanner-interface is missing
in the definition of TextSpanner (and several other grobs) in 
scm/define-grobs.scm
or is it rather that the arrow property is missing from the definition 
of the
text-spanner-interface in lily/text-spanner.cc?
