@darius Weird take: I very occasionally use -m with mercurial (I believe single line commit messages are almost never a good idea, but sometimes I do things that are not a good idea) but I NEVER use -m with git because it is completely baffling to me what files do and don't get included on any one git commit and entering the editor is the one surefire way to be CERTAIN you know what it is you're committing...!
