Maybe I'm the only one, but the new change in ls seems bad:

      set_quoting_style (NULL, shell_escape_quoting_style);

pvint@localhost ~ $ mkdir ls
pvint@localhost ~ $ cd ls
pvint@localhost ~/ls $ touch HelloWorld
pvint@localhost ~/ls $ touch Hello\ World
pvint@localhost ~/ls $ ls
'Hello World'  HelloWorld
pvint@localhost ~/ls $ ls -l
total 0
-rw-r--r-- 1 pvint users 0 Feb  6 22:35 'Hello World'
-rw-r--r-- 1 pvint users 0 Feb  6 22:35 HelloWorld

#### end paste from terminal  ####

I don't see the benefit to this change (partly because I'm a stubborn old guy who thinks "it's been this way for decades!"), but if there is a good one, I'll say "Cool, thanks!".

Cheers,
