I forgot to say why I didn't do this in the last release.
I noticed that who -a wouldn't be generally processable
due to the variable number of fields introduced with translations.
Also the number/format of fields would be quite consistent
between each class (who -u, who -d, etc.), and processing
across all classes (who -a) would not generally be useful.

Given Assaf's case was already handled with:
  LC_ALL=C who -u | sort -b -k6,6
I didn't think it worth changing the output format.
