I think it's only literal newlines -- so that if you want to actually
match a newline, there's still a way to do it.  (And since the idea
behind /x is to increase whitespace and readability, there's not much
advantage skipping over "\n" :-) Here's an example with a literal
newline:

  irb(main):003:0> /a
  irb(main):004:0/ b/x.match("ab")
  => #<MatchData:0x400d2ba8>
