...and not the way too large padding between the staff and the instrument 
name. But thanks for your hints, I could track down how bad the current 
defaults for InstrumentSwitch are:

-) no outsize-staff-priority => placed at fixed position
-) staff-padding set to 2, which means that the instrument name was placed 
half a staff away! I suppose 0.5 would make much more sense (or maybe 
somthing up t o1, but nothing larger than that! I find a spaff-padding of 1 
already too large.)
-) center-aligned on the note they apply to (=> unusable for longer names)


Attached is a patch, which changes the defaults for InstrumentSwitch to more 
sensible values:
-) outside-staff-priority set to 500
-) staff-padding reduced to 0.5
-) left-aligned on the note (actually, in the hand-engraved scores that I 
have, most fo the cue instrument names are neither center-aligned nor 
left-aligned on the note, but rather left aligned at the start of the 
measure...)

Okay to apply?


Unfortunately, there is still one case, where I run into problems: If I have a 
cue voice with #UP and a \set Voice.instrumentCueName to indicate the 
instrument name, then the first note is sometimes (in particular, when the 
beams/notes go outside the upper edge of the staff) stretched to the whole 
length of the instrument name. Attached is an example showing the effects of 
the patch: The instrument names are shown outside all other elements (due to 
outside-staff-priority set to a value as high as 500 to be outside of 
dynamics, too). The fourth measure shows the problem I described in this 
paragraph.

No, not about this issue. There was the missing side-axis of InstrumentSwitch 
(http://lists.gnu.org/archive/html/lilypond-devel/2008-02/msg00173.html, 
which only caused a warning, but no other problem), and there were collisions 
with the CombineTextScript grob, which was missing a setting for avoid-slur.

Cheers,
Reinhold

PS: If one leaves in center-alignment, the spacing problem becomes even worse: 
the first note of a measure will not start until the center of the instrument 
name, leaving huge gaps in there! To try it out, simply change LEFT to CENTER 
in the .ly file...
