Yep there's a lot of best practices you learn after using git for a while that is not obvious initially, like not using '/' in branch name (though, I used to have a coworker who always named branches like 'fix/something' or 'feat/something' -- well at least there was a pattern there).

I also don't use most of the git commands directly, I have a bazillion of aliases that are shorter and/or more intuitive.

To be honest, there were some changes for the better in the CLI. For instance 'git push' no longer defaults to the crazy 'matching' behavior, but 'simple' instead.

I guess the problem is perhaps that most of the time, people get used to the quirks and don't report them (maybe I'm mistaken).

In fact, if git bug tracker was hosted on GitHub, I'd probably be more active in reporting and discussing things. I'm not an old school mailing list kind of guy I guess, and maybe not only me (but I believe many git maintainers would say, it's a feature that barrier of entry is not low).
