This makes sure {a,b,} and {a,b,a,b,} are matched, but {a,b,c,} is
not. (only pairs)
Now, I want to extend this for any string and not just a and b. So, I
modify the above regex to
^((.*,)(.*,))+$
But it no longer matches only pairs. {ae,bee,} is matched but
{ae,bee,aer,} is also matched! I just don't understand why. What I am
missing here? I am using C#.
