What's happening there is that the same group is being used three times
to complete the match, but a group can only be represented once in the
output, so you are seeing the last substring that the group matched.
Contrast with:
>>> m = re.match("([abc]+)", 'abc')
>>> m.groups()
('abc',)
>>>
I don't *think* there's any way to introduce a variable number of groups
into your match, but I don't use re's that much so someone may be able
to help if that's what you want. Is it?
