Description of problem:
The man page for selinuxdefcon gives the synopsis as 
selinuxdefcon [-l level] user [fromcon]
but if the "fromcon" argument is omitted the behaviour is sometimes an error.


Version-Release number of selected component (if applicable):
libselinux-utils-2.0.80-1.fc11

How reproducible:
Generally

Steps to Reproduce:
1. type selinuxdefcon $USER at a command prompt
2.
3.
  
Actual results:
The behaviour varies maybe depending on context.

(Logged in via ssh)
$ secon
user: unconfined_u
role: unconfined_r
type: unconfined_t
sensitivity: s0
clearance: s0:c0.c1023
mls-range: s0-s0:c0.c1023
$ selinuxdefcon $USER
selinuxdefcon: Invalid argument

but

(in a vnc session)
$ secon
user: system_u
role: system_r
type: unconfined_notrans_t
sensitivity: s0
clearance: s0
mls-range: s0
$ selinuxdefcon $USER
unconfined_u:system_r:rpm_script_t:s0-s0:c0.c1023 



Expected results:
The first should output an selinux context (or a comprehensible error message)
