[coreutils] Bug: ls --tabsize=4

[Philip Ganchev]

Hi,

"ls" with a tab size other than 8 produces mis-formatted output in my
in Xterm, gnome-terminal and Linux console (see attached screenshots).
Though the output pasted from the X selection looks slightly
different, it is wider than $COLUMNS, and is not formatted as a table
no matter at what width it is wrapped.  This happens in Bash
3.2.39(1)-release (i486-pc-linux-gnu), and Zsh 4.3.4
(i686-pc-linux-gnu).
