It makes matching "non-greedy", so the pattern won't try to extend beyond the
first possible match.
In this particular case, the ? doesn’t have actually have any
effect — the longest string of digits that is immediately
followed by a dot is exactly the same as the shortest String of
digits that is immediately followed by a dot, since a dot is
not a digit. But the non-greedy modifier can be essential when
a repeated wild-card pattern would otherwise match right over
what is supposed to be the terminator.
That's correct, provided the shape of the actual data exactly
parallels that of the example but I've learned to take
precautions whenever possible. ;-)
