Subject: another strange regexp case

Hi,

here is another regexp behaviour which surprises me.
There may be some logic behind it, but I fail to see it...

irb(main):004:0> /(theone)?/.match(" theone").to_a
=> ["", nil]

irb(main):003:0> /(theone)?/.match("theone").to_a
=> ["theone", "theone"]

irb(main):005:0> / (theone)?/.match(" theone").to_a
=> [" theone", "theone"]

In the first case, it doesn't match "theone", but in
the second and third it does...

Could anyone explain this?

Kristof
