Double-flats used by Lilypond after transpose

[Jon]

Hi there guys,

I've been writing out a part for B-flat sax. I've written out the music in 
concert pitch and so am using \transpose to display it in the right key for the 
B-flat sax. The part I'm writing is in E-major when in concert pitch, so this 
becomes G-flat-major when transposed for the B-flat instrument. 

The problem I'm having is that Lilypond is choosing to use double flats for a 
number of particular notes when it prints out the B-flat part. For example, if 
I write a G or an F in the concert part (which is in E-major) these get written 
out as B-doubleflat and A-doubleflat respectively, in the B-flat instrument 
part, instead of as A-natural and G-natural, which would be easier to read in 
my opinion.

Is there a way to get around this problem - maybe to stop Lilypond from using 
doubleflats? Annoyingly, if I re-write my G as F-doublesharp it gets printed 
out as an A-natural when transposed - but I don't want to have to write my g as 
fss all the time as that will make working out what i've written a whole lot 
harder!

Below is some code which should cause this problem for you too! 

Besides this I would just like to say: great work - I'm really impressed with 
Lilypond. Thanks! Jon
