As suggested by jilles in https://reviews.freebsd.org/D17146:

> This is not wrong, but perhaps some details about different types 
> of errors may be helpful, such as that nonexistent usernames in -U 
> are immediately fatal while an empty result (such as from only 
> nonexistent process IDs in -p or only existing users that do not 
> currently run any process in -U) still writes the header line (if 
> not disabled) and also returns a non-zero exit status.
