Is line length the only issue you are looking at?  What about other
requirements of our logs and ChangeLog files, including those imposed
by authors.el?  The most problematic issue is when the file names
and/or its leading directories in the log message don't fit the actual
place and name of the file in the tree.  Did you look at those issues?
They typically come up when preparing a release tarball, and are quite
annoying at that time, especially if there are a lot of them, because
they require manual fixes.
