I'm not sure I've _ever_ used the -m flag to write a commit message. Naked `git commit` defaults to vim for me, and that's how I like it. Multiline messages, text turns from yellow to white when you go over 80 characters, summary of changes when you're writing the message, the ability to abort with :q! — I can't say the number of times I've realized I left a bug or forgot to tweak something or stage a change while writing a commit message, and bailed out to fix that before committing — the list of advantages goes on and on. I'll never not write my commit messages in vim, and I encourage everyone to do the same.
