What’s with the 50/72 rule?
It is part of common sense to assume that the worthiest commit messages lie far from any extremes. Years ago, I often fell in the trap of hastily sending a commit after commit, annoyed by the fact that I have to add a summary to it (let alone a description). I’ve seen many projects whose commit summaries consist primarily of one-word verbs like [FIX], [CLEAN], [TEST], etc.
They don’t tell much do they?
