    Fwiw, I do have plans to improve `ps' some more, but no intention
    for adding dramatic personality changes based on any environment
    variable. If the next version of POSIX/SUS describes such a
    variable, *then* we'll consider supporting it. That is the only
    context where it makes sense, imo. That's just my personal option,
    based on my previous experience with such variables.

    Note that I'll probably be tied up with "other matters" until
    April 15th or so, so don't expect to hear too much from me in
    the immediate future.
