Subject: POLS violation? /\s*/ no match at StringScanner end

Hi,

I've been bitten by this discrepancy on some occasions:

irb(main):003:0> StringScanner.new("").match?(/\s*/)
=> nil
irb(main):004:0> /\s*/ =~ ""
=> 0

Running: ruby 1.8.4 (2005-12-24) [i686-linux]

Is it a bug or a feature?! I can see arguments for both sides but for
me it violates POLS. Opinions?
