 operator makes the subexpression
minimal, or non-greedy.  Normally a repeated expression is greedy,
that is, it matches as many characters as possible.  A non-greedy
subexpression matches as few characters as possible.  Note that this
does not (always) mean the same thing as matching as many or few
repetitions as possible.
