New submission from Krzysztof Szawala <kszawala at slb.com>:

I am using optparse for command-line parameters parsing. To follow 
common naming convention I defined -d (minus followed by a single 
character option) and --debug (double minus followed by a word).

It looks like optparse doesn't complain when -debug (single minus) is 
specified and morover it doesn't recognize it as --debug.

I am using Python 2.5.2. Problem was observed on Linux but also occurs 
on Windows.
