What is it about our industry (or perhaps just the slice of it that hangs around HN) that makes people feel the need to spout absolutist dogma about trivial shit like whether a commit message should be a sentence or not? Jesus. Sometimes a sentence is the most useful and sometimes a very short newspaper-headline-style summary is the most useful. Why must we constantly go in search of hard rules that prevent this sort of consideration? If having to shift between styles makes commit logs too hard to read for you, maybe the commit messages aren't the problem.
