bug#25078: ls 8.26: discrepancy between `ls' and `ls -1' in the alignment of quoted and nonquoted items

[Zhiming Wang]

coreutils 8.26 includes the following improvement:

> ls now aligns quoted items with non quoted items, which is easier to read,
> and also better indicates that the quote is not part of the actual name.

which I find to be a welcome addition to the quoting behavior introduced in
8.25. However, this improvement does not apply to the -1 option, which is
puzzling to me. Compare the following (coreutils 8.26 on macOS 10.12.1,
80-column terminal, bash or zsh):

    $ ls
    '['
    'a very very very very very very very very very very very very long 
filename'
     b2sum
     base32
     base64
     basename

    $ ls -1
    '['
    'a very very very very very very very very very very very very long 
filename'
    b2sum
    base32
    base64
    basename

The second invocation with the -1 option leaves much to be desired in
comparison to the first invocation.

-1 should probably receive the same alignment treatment?

Best,
Zhiming
