ls -C broken

[Greywolf]

That would be rude on the part of GNU, that's for sure.

Below, though, I don't see the use of -C explicitly.  ls defaults to -C if 
output is to a terminal, and to -1 if not, as it has done for many years.

I see a lot of red herrings in the explanations below as regarding column, 
tabs, expand, and numfmt.  I don't think any of them come into play

Which version of 'ls' is pulling this nonsense?

Where is the -C?

Not strictly "required" but has done since forever.

GNU is getting too big for their britches.  This is completely out of line.
