bug#67765: ls: manual entry for -f mentions incorrect option

[Daniel Hofstetter]

Hi,

The manual entry for -f on
https://www.gnu.org/software/coreutils/manual/html_node/Sorting-the-output.html#index-_002df-9
contains:

"[...] This is equivalent to the combination of --all (-a),
--sort=none (-U), -1, --color=none, and --hyperlink=none [...]."

The "-1" option seems to be incorrect because "ls -f" lists more than
one file per line with ls 9.4.

Regards,
Daniel
