Exactly! I too have grown to like our ChangeLog style commit messages
enough that I use it in my own repositories.

I like to think of them as akin to the Pointing and Calling[1] system
common on Japanese railways. In the Pointing and Calling system, the
railway worker has to not only go through a checklist of items, but also
has to actually *point* (gesturing) and *call" (verbalizing) the
relevant dial or traffic signal. This explicit gesturing and verbalizing
makes them pay more attention and reduces the probability of an
accident. Likewise, our ChangeLog style commit messages force the
committer to explicitly list down the changes and thus catch any lapses
of concentration.

I agree! :-)
