command line option -F is not working on Windows cmd

                 Key: JRUBY-3681
                 URL: http://jira.codehaus.org/browse/JRUBY-3681
             Project: JRuby
          Issue Type: Bug
          Components: Windows
    Affects Versions: JRuby 1.2
         Environment: Windows XP
            Reporter: Zemian Deng


The following work on Windows with native Ruby:
{{
D:\>ruby -e "5.times{ printf(\"%.3f @ %d\n\", rand, rand(100)) }" | ruby -naF"@ 
" -e "puts $F[1]"
70
33
23
12
53
}}

But when running with jruby, I get this:
{{
D:\>jruby -e "5.times{ printf(\"%.3f @ %d\n\", rand, rand(100)) }" | jruby 
-naF"@ " -e "puts $F[1]"
jruby: unknown option -naF@
}}

I tried many way to use the -F option but could not get it to accept. Is this a 
bug?

Thanks,
Zemian
