Description of problem:
It seems that telnetd/setproctitle.c sets up a string long as args +
environment, then it proceeds to fill with blanks what's after the
last useful chars (ie: hostname).

The primary effect of this is that /proc/X/cmdline has many blanks at
the end (espacially if you have a bing environment)

The side effect of this is that when you do "ps ax|less", "ps ax|more"
(but not simple "ps ax" or "ps ax > file") output will look like

Version-Release number of selected component (if applicable):
telnet-server-0.17-26


How reproducible:
Always


Steps to Reproduce:
1. "ps ax|less"
2. look at the output

Actual Results (blank lines in output): 
========
 1117 ?        SW     0:00 [kjournald]

Expected Results: 
=========
 1117 ?        SW     0:00 [kjournald]
13127 ?        S      0:00 in.telnetd: myhost
