I've not tried, because I don't need to.  I've done considerable work with 
print-outs and a ruler, and was able to confirm that, unless line-width is 
scaled as I propose, then the actual width of the incipit, including the 
instrument name, is too narrow, by the factor quoted.  This is obscured to 
some extent by setting the instrument name right-aligned, but if you align 
it left, it shows it in the wrong place.

See the attached images.  The first is created with a left-aligned 
instrument and scaling applied to indent to get line-width.  You will note 
that the instrument name is aligned to the left of the page, as it should 
be.  The 2 bars are 3 cm and 8 cm wide, which is what was set in the layout 
block of the parent score, demonstrating correct alignment.  The second is 
shown with line-width unscaled.  You'll see that the instrument name is too 
far right: this is because line-width is too short.  So it's clear that the 
problem is _not_ that we need to change incipit-width to scale this down (as 
indent and short-indent are) but to rescale indent back up to be the right 
size.

I have spent a long time checking this.  If you can come up with a better 
system that makes indent within the layout block the size it was originally, 
then fine.  Otherwise, please stop arguing that the wrong variable is being 
scaled.
