This bug was reported here: https://github.com/nex3/sass/issues/104
Added test for patch to fix https://github.com/nex3/sass/issues/104

Note that Ruby 1.8.7 should be used when running this test, as 1.9 will pass regardless of whether the fix has been applied or not.
Added comment as requested, and cleaned up code

We now check that at least one group was matched, and we raise (a programmer
error) if that group does not occur at the end of the matched string.
Make sure we use Float instead of Rational with mathn.
