Oh, I see what you mean -- but yes, they are included.  Hmmm... I was
going to say, use a literal instead of %r{} to get the comments in,
but that seems not to be available:

ruby -e 'p /abc
#blah
/x'
/abc\n#blah\n/x

All I can think of is:

  irb(main):003:0> /ab#{"This is a comment"*0}c/.match("abc")
  #<MatchData:0x401e3990>
