In my line of work a bug could cost multiple millions. I do read them. I write long ones. I would love if my colleagues started writing longer ones too.
Most of the times, the commit message is 10+ lines while the change itself is -1/+1.
We use GitHub for repo hosting and a separate issue tracker to coordinate changes. It bothers me a lot that GitHub UI doesn't render markdown for commit messages. We all write really detailed and nicely formatted commit messages, and had to work out a commit message sync so the issue tracker can display related commit messages in full Markdown glory.
