Some maintainers do not care about bloated sizes of the commit messages,
however there are several advantages to have them shorter:

1/ saving resources (followed by disk storages and energy around the world,
   means being environment friendly for real);

2/ when reading log, noise make it much harder to understand, besides the
   fact that reading itself will be time consuming;

3/ nowadays some people are tending to read or even discuss the changes on
   the mobile devices, where screen size is not so big;

4/ the copied'n'pasted backtrace means that the contributor probably
   haven't thought through it and the quality of the change is in doubt.
