Package: coreutils
Version: 8.32-4+b1
Severity: normal

Dear Maintainer,

Quoth who(1):
-- >8 --
       -s, --short
              print only name, line, and time (default)
-- >8 --

Compare who -H:
-- >8 --
NAME     LINE         TIME             COMMENT
nabijaczleweli pts/0        2022-07-31 14:33 (192.168.1.109)
nabijaczleweli pts/2        2022-07-31 16:22 (192.168.1.109)
nabijaczleweli pts/3        2022-07-31 16:22 (192.168.1.109)
misio    pts/4        2022-07-31 16:23 (192.168.1.1)
-- >8 --
(and note that the columnation is broken like in pinky (#1016117)).

Problem 1: <name> <line> <time> is not the default output.

Quoth POSIX Issue 7:
-- >8 --
-s
    [XSI] [Option Start] List only the
    <name>, <line>, and <time> fields.
    This is the default case. [Option End]
-- >8 --

I think it's reasonable to have the default output also have <comment>,
but it's non-conformant to have no way (I think?) to hide it.

This also contradicts the manual.

Best,
