You sure this works?

$ ruby -e '$/="\r\n"; puts "foo", "bar"' | od -c
0000000   f   o   o  \n   b   a   r  \n
0000010

Output record separator doesn't seem to help either:

$ ruby -e '$\="\r\n"; puts "foo", "bar"' | od -c
0000000   f   o   o  \n   b   a   r  \n
0000010

Explicit works:

$ ruby -e 'print "foo\r\n", "bar"' | od -c
0000000   f   o   o  \r  \n   b   a   r
0000010

$ ruby -v
ruby 1.8.5 (2006-08-25) [i386-cygwin]

Hm...  Is this a bug in Ruby 1.8.5 or am I missing something?
