Re: Typos in the comment for the estimate_multivariate_ndistinct()

Hi,

While reading the estimate_multivariate_ndistinct(),

 I think "If a match it found, *varinfos is

 * updated to remove the list of matched varinfos"

should be "If a match is found, *varinfos is
 * updated to remove the list of matched varinfos"

I've attached a patch for that.
