changeset comment Contributed-by: line

The description of the Contributed-by: line in http://openjdk.java.net/guide/producingChangeset.html is simply: The contributed-by line is optional. That doesn't provide much guidance. Can someone update it to this (or something similar)? The contributed-by line is optional; if present, it is a list of comma-separated email addresses. It should be included only if the author of the code does not have commit rights to the target repository, and thus would not otherwise receive acknowledgement. -John
