Aha... now I understand.
To take this hairsplitting exercise a little further, there is a slight
difference between ruby and irb here:

[alex@dhcp-89-2 alex]$ ruby
%s
 
-:2: empty symbol literal
[alex@dhcp-89-2 alex]$

[alex@dhcp-89-2 alex]$ irb
irb(main):001:0> %s
irb(main):002:0:
irb(main):003:0>
SyntaxError: compile error
(irb):2: empty symbol literal
        from (irb):3
        from :0
irb(main):004:0>

So, ruby sees an error after two linefeeds, while irb does it only after
three.

Although, if I make a file out string "%s\n\n", both interpreters behave
the same on it...

I hope everybody can live with this :)

Best regards,
Alex
