Subject: regexp#options in 1.7.2

Regexp objects in Ruby 1.7.2 have an 'options' method.  Poking around, I se
that it returns an integer version of the options flags, but can't figure
out what the bit in position 8 (assuming far right is position 1) is
supposed to be:

  re = Regexp.new("ruby", Regexp::IGNORECASE | Regexp::EXTENDED)
  p re.options                  # 131  (000000000000000000000000010000011)
  re = Regexp.new("ruby", Regexp::IGNORECASE )
  p re.options                  # 129  (000000000000000000000000010000001)

I couldn't find any regexp constants defined for 128.  What is this value
for?


Thanks,


James
