I've never the GitHub editor/UI to submit non-trivial changes which require more than a few words to describe. I do not need vi to write "Fix a typo in the documentation". Is it you or the project owners who care about the 72 character limit? IME most projects will accept contributions regardless of formatting of the commit message. Most people are just happy about contributions, regardless of source.
