Right. But that's the limit I don't get. If I always have to view the expanded set of commit messages to understand anything about the commit, what's the value in a short subject? And why 50 chars? That's even more restrictive than the normal 72/76/80 chars.

I think a limit is helpful to keep the subject line short, but I frequently (like, daily) struggle to fit useful messages into only 50 chars. Personally, I find 72 chars to be the sweet spot.

I wish GitHub or Azure DevOps made this configurable (because I use them) - anyone know if any other hosted git systems have this as a configurable option?

[nirvdrum]

I'm in favor of a team being able to set a limit if they'd like and tools adapting. Personally, I'd rather a 90 char commit message that conveys useful info than a contorted message intended to fit in 1/3 the size of an SMS message.

It's so that when you print the git-log graph, you don't end up with wrapping of the subject text for deeply-nested trees.

Also, in the kernel generally you reference a different commit in a commit message with the form 'commit <12 char commit id> ("subject")'. So further restricting it makes sense.

[nirvdrum]

Okay. But I contend that makes the whole log worth less because the short commit messages are often devoid of useful info. Granted, I don't have an email-based patch workflow; I look at logs on both GitHub and pulled in from the CLI. On GitHub, things are even worse because I have to constantly expand commits to see what actually changed.

In any event, I think teams should be free to adopt the workflow that works best for them without tools getting in the way. GitHub wrapping commit messages at 70 chars, even though I have more than plenty enough horizontal real estate, isn't helping anyone.
