The old behavior had not a problem at all. There was no need for re-thinking  
ls' purpose of existence, like "What is actually the idea of ls? ... if the 
idea is A, B or C then change X, Y or Z". What about "If most users like it 
as is then no need to change anything."?

Most other ls other implementations still do not have any problems. coreutils 
ls is now an unusual one by default. We have had many nice options to 
_enable_ and select different quoting styles. The only problem is that the 
default behavior changed. However this fact is ignored since months. Maybe 
you should add an FAQ, like:

Q: Why is ls ugly now?
A: It is not just ugly but also better! Imagine if you would like to 
copy/paste file names! It was possible in past using extra complicated 
options only but now even by default. Never thought about this? Just try to 
copy/paste, no need to read the ls output anymore. All your experience that 
ls was good as is since 20 years is wrong. BTW in the next release we will 
copy the ls output automatically into the clipboard without printing anything 
into the terminal (Then nobody can complain about ugly output anymore.)
