Description of problem:
On both my KVM hypervisor system as well as on the guests,
"rhn_register -v" ignores the switch and starts the GUI.
"rhn_register --version" functions as expected.
Version-Release number of selected component (if applicable):
rhn_register (Red Hat Network Client Tools) 0.4.20-9.el5
Steps to Reproduce:
1. rhn_register -v
2. rhn_register --version
Description above is in fact correct behavior.
According to program manual page as well as --help message, -v switch
is a short option for --verbose, not --version.
