Actually, I don't know if this is a bug. But, when I set tabs to 4 in bash

$ tabs 4

then ls (without the color flag) a big directory, such as /usr/bin

$ alias

$ ls /usr/bin/

(lots of white text)...

Compare to when I use color flag...

$ ls --color=auto /usr/bin/

The indentation didn't broke at all.

If this is a bug, please fix it. Thanks!

It's not something 'ls' can easily fix, because 'ls' can't deduce from the operating system that you have installed nonstandard tab stops.

I installed the attached to try to document the issue.

Messing with hardware tab stops is typically more trouble than it's worth. I think the last time I did it was back in the 1970s, with a IBM 029 keypunch drum card. Back then it sort of made sense, if you were programming in assembler or FORTRAN 66. Nowadays, not so much.
