The number of commits doesn't necessarily tell how significant was the
contribution; you need to count the number of added/changed lines
instead.  As an extreme example, the original author who write a
package from scratch and installed it in a single commit will be at
the tail of your list, but that doesn't express correctly the
contribution of that person.
