Hi,

Here is an automatic way to do what you want.
We override the `stencil' callback for InstrumentName, in order to
set the line-width property according to the line indent before
interpreting the instrument name markup, which is more usefull than
having the full line width.  This way, \fill-line will work as expected.
This should be the default, imho.
