Here's what I ran, same dir as running rake

puts( system( %{rdoc -o doc --main 'README.rdoc' -T 'html'  README.rdoc
                    ./lib/catapult.rb ./lib} ) )
puts( $? )


and here's what I get:
false
nil

So it fails, but there's no residue. :(

It appears to be related to rdoc on windows being called through rdoc.bat

I wrote a simple batch file, foo.bat:
  REM foo.bat
  dir

and tried this Ruby code:

puts( system( %{foo} )  )  # false, doesn't seem to find foo.bat
puts( $? )     # nil

But this correctly calls foo.bat:

puts( system( %{foo.bat} )  )  # prints directory, then true
puts( $? ) 		       # 0


So I added the '.bat' extension to the rdoc call, and 'system' is quite
happy:

puts( system( %{rdoc.bat -o doc --main 'README.rdoc' -T 'html'
               README.rdoc ./lib/catapult.rb ./lib} ) )  # Works!

Thanks.
