This matches NetBSD, and also seems to be what linux does. The sentence

error). This makes the -l and -s options more consistent, like
Solaris and (Debian) Linux. To make this happen, tweak two
optimizations on the second call to display():
- Don't skip display() altogether, even if list == NULL.
- Don't skip the call to the printfn in display() if we
need to print the total.

compile-time option, where:
ps -options arg1 arg2
(with no '-' on "arg1" and "arg2") was treated as:
ps -options -N arg1 -M arg2
This also changes `ps' to check for any additional arguments after
processing all the '-'-options, and attempt to use those arguments as
a pid or pidlist. If an extra argument is not a valid pidlist, then
`ps' will print an error and exit. This seems a more generally useful
extension of the kludge-option processing than the -N/-M behavior, and
has fewer confusing side-effects.

This is an often-requested feature.
Use wcwidth() to determine the number of column positions a character
takes up, although there are still a few places left where we assume
1 byte = 1 column position, e.g. line-wrapping when handling the -m option.
The error handling here is somewhat more complicated than usual: we do
our best to show what we can of a filename in the presence of conversion
errors, instead of simply aborting.

This corrects a problem of lost-precision for `-r' (sort-by-CPU). Also,

- Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
- Add the `-G gidlist' (group id).
- Allow any of these "selector options" to be specified multiple times,
and have `ps' keep adding to a given list -- instead of replacing the
previously-specified values.
- Fix interactions between selector-options, so that: "If any are
specified, ... ps shall select the processes represented by the
inclusive OR of all the selection-criteria options." (from SUSv3)
- Add a `-X' option, which is the reverse of the `-x' option.
