Bug#2159: "ps pids" lists more than just pids

[Robert Leslie <rob@advantage.org>]

Package: procps
Version: 0.98-0

The ps man page says:

       ps  [-]  [lujsvmaxScewhrnu]  [txx]  [O[+|-]k1[[+|-]k2...]]
       [pids]

       ...

       pids List  only  the  specified processes; they are comma-
            delimited.  The list must be given immediately  after
            the  last  option  in a single command-line argument,
            with no intervening space, e.g.  ps  -j1,4,5.   Lists
            specified in subsequent arguments are catenated, e.g.
            ps -l 1,2 3,4 5 6 will list all of the processes  1-6
            in long format.

But, ps shows other processes in addition to what I ask for:

deimos:~/proj/debian:[812]% ps 1
  PID TTY STAT  TIME COMMAND
    1  ?  S     0:13 init [2]
 2329 pp0 R     0:00 ps 1
13776  ?  S     0:10 fvwm
13788  ?  S     0:00 xclock
13789  ?  S     0:00 xload
13797 pp0 S     0:07 -zsh
13822  ?  S     6:10 emacs
13828  ?  S     0:00 /usr/lib/emacs/19.29/i486-debian-linuxaout/wakeup
16975 pp4 SW    0:00 ftp
22415  ?  S     0:17 /usr/local/etc/afpd
31599  ?  S     0:27 /usr/local/lib/netscape-2.0b5/netscape
32486 pp1 S     0:00 rlogin
32488 pp1 S     0:00 rlogin

(It looks like the extra processes are what I'd get if I didn't specify any
pids on the command line.)

Also, "ps --help" doesn't mention being able to specify pids:

usage:  ps -acehjlnrsSuvwx{t<tty>|#|O[-]u[-]U..} \
           --sort:[-]key1,[-]key2,...
           --help gives you this message
           --version prints version information
