Given foo.rb with the single line:  
puts $FILENAME

Run, under Ruby 1.9:  
ruby foo.rb asdf

Gets error:  
foo.rb:1:in `’: No such file or directory - asdf (Errno::ENOENT)

This duplicates the way the Rails passes the webserver name (ie  
“script/server webrick”)

Under Ruby 1.8.6, I get the output “-”; no exception.

Is this a problem with Ruby 1.9, Rails, or something else?
