Vim: Quit with an error code (eg. to prevent Git from committing)

Nice. Suggested mnemonic, "cancel-y quit"... "commit quitter"...

I've just had been leaving an empty commit message; git then cancels the commit.

Brevity is the soul of vim. :-) Great tip.

@alxndr: "Call-it quits", maybe?

You can also quit without writing to avoid a commit. This command is nice because it's useful in lots of situations.

:q!

Caution: your changes won't be saved by :cq

Watch out! If you're doing a git commit --amend, then you need :cq, otherwise you'll regenerate the commit with the same message (if you already pushed... d'oh).
