Yes, (chuckling and laughing), but I don't think you read the help
output!  In the help output it says explicitly how to remove files
that start with what will appear to a program to be a command line
argument.  You even included it in your message to the mailing list!

Please go read the help output again.  It tells you everything you
need to know to remove files that start with a dash.  The FAQ here has
a more complete explanation of your problem.


Hope that helps.
