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.
