Use BufDelete or similar instead of BufWritePost in :GitCommit

[wincent]

When writing a lengthy commit message you might want to save the buffer occasionally out of habit, but if you do you'll find that a commit takes place and your half-written commit message got included.

To avoid this, I think it would be a good idea if the BufWritePost autocmd in the :GitCommit implementation were changed to BufDelete or similar.

It would also match the behaviour of the command line when you have EDITOR=vim (or any other editor) in your environment and do a "git commit": the actual commit is only processed when you exit the editor, not when you save the message.
