Just look at the start of this thread.  Some people put
the [PRnnnnn] only in the first line of the commit.  And that is
what these changes want to diagnose, that is an error and results
in bugzilla not being updated.
The current changes won't do the other direction, i.e. if there
is a PR line in the ChangeLog entry complain about [PRnnnnn] missing
in the first line.  The fact that it isn't required by the script doesn't
mean people shouldn't do it, but if they occassionally forget, it is not
that bad as not mentioning it in ChangeLog.
