Fix for bug 102487: If you had "comment on product change required" turned on in your installation, Bugzilla would warn you of
a forgotten comment AFTER allowing you to choose new components, versions, and milestones, forcing you to hit your back button
TWICE to correct your mistake.  This checkin corrects that.
