213 * Okay. Umpteenth attempt at doing this, so let's re-comment...
214 * For local users (/w localuser), we show idletime if hidewhois is disabled
215 * For local users (/w localuser localuser), we always show idletime, hence parameters.size() > 1 check.
216 * For remote users (/w remoteuser), we do NOT show idletime
217 * For remote users (/w remoteuser remoteuser), spanningtree will handle calling do_whois, so we can ignore this case.
