Most of your "unix" commands are probably using GNU getopts. 

However, the standard Python option parser allows you to act consistent with other unixes.

http://docs.python.org/lib/optparse-other-methods.html second bullet.

"This restores traditional Unix syntax, where option parsing stops with the first non-option argument."
