[Toybox] [PATCH] ls: Ensure file names are separated by 2 spaces

[Andrew Ilijic]

Hi Jarno,

Thank you for your email. It caused me to learn a lot about Unicode
today. I still need to collect my thoughts but I wanted to respond to
your email. I tried throwing all kinds of crazy Unicode at XTerm,
Gnome Terminal, and Suckless Terminal. I don't think any of them do
the "right" thing in all cases but, XTerm seems to be the best. `ls`
seems to be handling combining characters well. I am going to compare
how `cut` and `ls` handle clipping the string. I have started to
implement the column (`-w`) option in `ls` so I may shoot you an email
if I have questions.
