Subject: Is this a ruby bug?

In the following code, the line marked #bad# only finds '.' and '..' 
directories.  But the line marked #good# finds all the subdirectories.

I tested this in the same directory, passing the same argument (even so 
far as using the UP arrow key to avoid typo differences).

Is this a bug in Ruby 1.8.2 snapshot?  Should the two lines produce the 
same results?

#ruby

def dirloop(rootdir)

	
#bad#	Dir.foreach(rootdir){|dir|
#good#	Dir[rootdir + "/**/*"].each{|dir| 	

		if(FileTest.directory?(dir)) then
			puts "found directory #{dir}";	
		end
	}	
end
			
rootDir = ARGV[0];
puts "starting at root directory #{rootDir}";
dirloop(rootDir);
