Let's ask Ruby:

Neo:~/Desktop$ cat multiline_data.rb
#!/usr/local/bin/ruby -w

data = DATA.pos

p DATA.readlines

DATA.seek data

p DATA.read.split("\n")

__END__
Line one.
Line two.
Line three.
Neo:~/Desktop$ ruby multiline_data.rb
["Line one.\n", "Line two.\n", "Line three.\n"]
["Line one.", "Line two.", "Line three."]

If you go back and look at the original code now, I was hoping that  
would save all the random calls to strip() when Hash data is  
accessed, thought the "=" split() pattern may also need to become / 
\s*=\s*/ to get leading whitespace.
