repeating ending numbers

[Paul Scott]

With 1.7.20 if a first ending goes to the next line the ending number is 
repeated.  I have never seen this in printed music and I believe it 
makes the music harder to read.  For someone who often is in a sight 
reading situation I find this an unnecessary distraction.

Thanks,

Paul Scott
